The World Cup is upon us and there are some reasons for optimism about the England national team. The side made it through qualification without breaking a sweat, conceding only three goals across ten games, and contains some of the most exciting attackers in the Premier League. One significant area of concern, however is central midfield. Looking through the team, it's difficult to find anyone who naturally excels in the all-around central midfield role. Jordan Henderson and Eric Dier are most accustomed to playing at the base of a midfield. Dele Alli and Jesse Lingard are used to playing in more advanced roles closer to the forward line than the midfield. There’s Ruben Loftus-Cheek, a central midfielder by trade, but one who has only experienced one season of regular senior football, and it was on the left of a four man midfield. Then there’s Fabian Delph, a natural midfielder who has just had the season of his life at left back. The days of Paul Scholes, Steven Gerrard, and Frank Lampard are long gone. Dealing with this issue seems to be at the heart of manager Gareth Southgate’s formation switch. After sticking with a solid 4-2-3-1 throughout qualification, he has largely embraced a 3-5-2 system since then. This is not the 3-4-3 system Southgate experimented with at times in 2017, instead it's a formation which noticeably uses a midfield three. In the friendly against the Netherlands for example, Alex Oxlade-Chamberlain and Jesse Lingard (numbers 7 and 11 in the picture) were generally found level with each other, alternating at taking more advanced roles. 
Out of possession, the full backs generally moved into more defensive roles next to the centre-backs, leaving the three central midfielders to screen the back line. 
While in possession, one of the forwards (more often than not Raheem Sterling, number 10 in the image) will frequently drop into a deeper role, creating space for the two central midfielders to advance. 
This system demands a lot of energy from the central midfielders. They need to move into more advanced roles assisting the attack while also returning to their roles in a quite a defensive shape without the ball. Plenty of athleticism will be required. And while the shape is clearly designed to mitigate the problem of a lack of creative passers in the England squad, any ability to help transition the ball forward will be of great use. As such, let’s take a look at the options:
Ruben Loftus-Cheek
Perhaps surprise inclusion in the squad, Ruben Loftus-Cheek’s skillset is fairly wide-ranging and atypical of a central midfielder. Despite being a full six foot, three inches tall, Loftus-Cheek has a lot of mobility and was able to be an important transition player on the left of Crystal Palace’s 4-4-2 system this season. While nominally playing out wide, Roy Hodgson’s system was often so narrow that he ended up in positions more commonly associated with the central role he has played for Chelsea’s youth sides. In that role he turned into a surprisingly productive dribbler of the ball. While hitting 3.5 dribbles per 90 at age 22 is a strong but not exceptional figure (the research has long indicated that players peak early in terms of volume of dribbles), many players can be generally wasteful with this. Loftus-Cheek avoided that pitfall, consistently managing to recycle the ball well after dribbling, leading to good counter-attacking opportunities for Palace. The data gathered by StatsBomb's own Euan Dewar shows the Englishman as one of the more productive dribblers around, and this is evident from watching him.
Fabian Delph
After spending his career as a solid but unremarkable central midfielder for Aston Villa and then Manchester City, converting to left-back led to his emerge as a valuable cog in Pep Guardiola’s machine. At first glance. the decision to include him in the squad as a central midfielder then may seem poorly thought out, but it does make tactical sense. Ever the innovator with fullbacks, Guardiola generally instructed Delph to move inside to a central midfield role alongside Fernandinho in possession, with Kyle Walker at right back shuffling in alongside the centre-backs (John Stones and Nicolas Otamendi for the first half of the season, though he has shuffled the pack since) to form a back three behind them. Southgate is well aware of that structure, and, in fact, referenced it while explaining his decision to play Kyle Walker at centre-back, saying, “he ends up in that area anyway." It’s not a surprise to see the England manager interpret Delph’s role similarly. The familiarity of Delph, Stones, and Walker all playing roles in a defensive unit structured similarly to Manchester City’s could be of use when international football generally doesn’t allow players the time to form strong relationships on the pitch. What’s less exciting about Delph is what he does on the ball. At City he is fortunate enough to play alongside two of the best creative passers on the planet in Kevin De Bruyne and David Silva. Delph can keep his passing relatively simple and letting those two run the show (and with Guardiola’s strict positioning, there are always a number of options available). England would require him to be a more creative outlet, which is something he’s never been able to do to great effect. As such, he might be more suited to playing in the knockout stages, against higher quality sides who will look to dominate possession, when England will need to retain a strong defensive structure before using players like Sterling and Kane on the counter.
Jesse Lingard
While he is not someone who might be seen as a central midfielder in, say, a 4-2-3-1, Southgate’s system does allow for players who function closer to what is now being described as a “free eight”, with the licence to play as something more akin to a number ten a lot of the time than a “true” midfielder. Lingard has played in a number of roles this season, but looked particularly dangerous playing as a free eight in Manchester United’s 3-1 victory away to Arsenal in December. The attribute Lingard probably excels at the most is pressing, with Will Gurpinar-Morgan’s research putting him as the best player in the Premier League at regaining possession via pressure, and second best at applying pressure generally. What’s interesting is how much he does this across the pitch rather than in any one specific area, as shown in this graphic: 
Pressing ability is usually thought of in terms of energy and work rate, qualities Lingard has in abundance. But what is also key is the intelligence to take up the right positions to pressure the opposition player on the ball, and this is what really makes him special. This excellent positional work is to be seen in an attacking sense as well, with his 0.39 expected goals per 90 minutes the best of the players on this list. A lot of Lingard’s goals this season have come from him managing to slip away from defenders to find space for a shot, even in a congested penalty area. Lingard’s off the ball work is outstanding, but his on the ball actions don’t quite reach the same heights. His 1.18 key passes per 90 is unimpressive when one considers he’s an attacking midfielder for a team as stocked with attacking talent as Manchester United. Juan Mata, Alexis Sanchez, Anthony Martial, Paul Pogba, and the shipped out Henrikh Mkhitaryan were all better chance creators for the same United team this season. When watching Lingard, he does sometimes have the frustrating tendency to favour the safer passing option, and his passing accuracy of 87.8% is more indicative of a limited range than anything else. It seems as though he’s most suited to high tempo, frantic games, while one imagines England’s first two fixtures against Tunisia and Panama will not fit that mould.
Dele Alli
The most established player on this list and yet paradoxically the youngest. He’s coming off a season where his goal scoring work declined somewhat (0.30 expected goals per 90 compared to 0.43 the season before), but was balanced out with greater work in terms of chance creation and a strong all-around game. Alli hit almost identical xGChain in both years. He's a more than able presser, coming up not too far behind Lingard in Gurpinar-Morgan’s “possession regains via pressure” metric. Like Lingard, part of the reason for his good pressing work is in the intelligent positions he takes up, and that is one area where he measurably stands out. Looking at StatsBomb’s data for actions under pressure, Thom Lawrence showed that no player in the Premier League last season had a lower percentage of his passes made or received in the final third “under pressure”. The implied value in this is that Alli appears to be particularly adept at evading pressure from opposition players in the final third, being able to find areas of space even in an often congested zone of the pitch. 
This excellent appreciation of space is probably the thing that sums up Alli’s game the best. His passing is useful, but this comes less from superb technique than good tactical intelligence that helps him find teammates in space. Part of this is from a good understanding with the other Spurs players, and while this would typically be a negative for a player in an international side, that won't necessarily be the case give how many of his Tottenham teammates are in the England side. Harry Kane is likely to be the fulcrum of England’s attack, with boths Kieran Trippier and Danny Rose probably providing delivery from wide areas. Adding another important Spurs cog in Alli could help England to have a more coherent attack than many nations selecting players from a number of different clubs.
Conclusion
With Southgate opting to start Lingard and Alli in Saturday’s friendly against Nigeria, it seems likely that these two are his preferred options in midfield. This is deserved on merit, with the two of them being the best performers of the options in the Premier League last season, but there are concerns over their fit. Both are active pressers who look to make intelligent runs off the ball and get into dangerous positions, and neither of them are associated with a lot of creative passing or dangerous dribbling through midfield. In this regard, there’s a serious case for playing Ruben Loftus-Cheek in the first two games, who has at least shown a penchant for dribbling forward through midfield and generating fast attacking chances for those in front of him. Conversely, against the better sides in the knockout stages, Fabian Delph has a strong argument for playing, having looked comfortable all season in a defensive unit with Kyle Walker and John Stones. As such, a fair amount of mixing and matching throughout the tournament could be the best approach. (Header photo courtesy of the Press Association)
