Transfer rumours are hot and heavy on Monaco’s Kylian Mbappe this week. Some might even call the speculation “furious”. Manchester United have allegedly tossed £72M at Monaco. Real Madrid today are rumoured to be on course for an £85M move (which presumably means Benzema or Morata are leaving, and half the deal will be recouped through selling one of them).

Mbappe is 18 years old. He has also had a torrid – but somewhat lucky – season at Monaco this year. Today I want to briefly walk through his underlying numbers and discuss what valuation I would put on him in the transfer market.

Previously I helped on a couple of real world deals for high profile players that were negotiating new contracts, and this type of valuation process proved very valuable and lucrative there.

The Stats
Kylian Mbappe - French Ligue 1 - 2016-2017_5may

Kylian Mbappe - shotmap - 5may2016-2017

Mbappe is already an outstanding scorer, and the fact that he’s well-rounded and not just a poacher is hugely impressive. On the other hand, he’s currently scored double his expected goals. If you think he’s going to score a goal a game, you will likely be sorely disappointed.


Half a goal a game of xG is excellent. MBappe is already a significant outlier for players under 23 across Europe. Don’t be disappointed he’s not the greatest player in the world right now. Be very very excited that even without the overperformance, he’s already one of the better scoring forwards in Europe at age 18.

The Eye Test
Mbappe plays in a good-but-not-great league, and he’s shown the ability to terrorize some of the best defenses in the world in the Champions League. In the first 25 minutes against Juventus, he gave the entire Juve back line fits with pace, power, and movement. 

Having watched quite a few Monaco CL and league matches this season, I can also tell you that Mbappe regularly produces exciting moments of skill that would be fantastic from a 25-year-old. The fact that he’s out there doing it at 18 against grown men is staggering.

Oh… and he’s So. Damned. Fast.

Valuation Discussion
Given what we know above, the question now becomes what value do you think Mbappe should have. Ignore for a second that we only have this one season of data. Assume Mbappe’s baseline stats are rock solid, and we can expect him to produce .5 xG per90 for the next 7-10 years.

The value on that is at least £50M. Factor in the fact that he has a lightning first step, can dribble, and also knows to keep his head up for a pass and now we’re past 60M.

Then there’s another factor. What if Mbappe really is Thierry Henry Mark II? Or Ronaldo (either the Brazilian or Portuguese one)? He’s still maturing, but player development is uncertain. Maybe right now is Mbappe’s peak but – just maybe – his peak is legendary.

Well we know for a fact that Ronaldo and Messi and Henry in their prime would be valued somewhere between 150M and You Can’t Buy This. Let’s estimate an approximate fee in those situations to be £200M. Subtract the 60M mark we already have and you get £140M of “potential pricing.”

The question then becomes what probability you assign to him reaching that legendary status.

Say your scouting group loves Mbappe as he is, but it’s only 20% likely he’ll become a Ballon D’or winner. The calculation is then 60M (actual) + 28M (legend potential) = 88M. If you are able to buy him for 88Mish, you are in good shape.

Now there are other factors at play that change the price equation, like Mbappe is SO YOUNG that even after a 5-year deal, he’s still only going to be 23, meaning you might not need to spend another 100M then, so maybe that moves the price up.

But maybe you are really concerned that we only have one year of data for the kid, and Monaco are a bit weird and overperforming expected goals massively, and he’s playing for a super team and…

Then maybe that increases your risk assessment and you drop the price you are willing to pay because of it.

This skill set from a fully grown player is rare. This skill set from an 18-year-old is absurd. Given the fact that Mbappe could produce .8 or .9 xGA a game for the next decade, it’s not unreasonable to put a £100M tag on him right now. Preferably the base fee is a bit lower with huge add-ons, but unless there is a release clause in his contract, Monaco have a very strong hand to play in negotiations and can demand an awful lot of cash up front.

Anyway, I thought this case was really interesting to analyse through the context of how I would think about it inside of club recruitment. I hope you enjoyed it, and if you find yourself needing professional help in this area, get in touch.

    Do you think Monaco might look to build a team that wins 3 out of the next 5 L1 tittles? I know their plan since the money went was to build up players to then sell them, but they have so many good/great players at the moment. If not, how many do you think will go during the next window?

    • Illmatic27

      Monaco best young talents that makes the core of that team are – Lemar, Bernando, Fabinho and Mbape
      I guess if they sell Mbape they keep 3 other players or at least 2, if they wont to keep Mbape they might need to sell them all

        If you set a price for Mbappe at 90-100 and someone offers it, you have to consider that regardless of who else is going. He could cool off next season and be worth half that.

    I Belive that the market situation is going to have a huge role on this trade this summer: all the biggest team (in term of cash) are going to be really involved in this trade for multiple reasons:
    1. Both Manchester teams have great managers with the power to “convince the owners” to big spending…
    2. Paris Saint Germain sees the occasion to take the best france player of the next decade, and grow it’s internal market share
    3. Barca could be in it’s first season without a (meaningful) title from a while
    4. Madrid it’s Madrid, and spending big for a great player on summer it’s mandatory to retain it’s status on merchandise and press…
    5. Liverpool and Chelsea are (probably) back in the UCL stage, and with big-hype managers too
    6. Arsenal is probably going to change manager and in need of a big move to remain relevant.
    In the end I believe that this situation it’s going to exploit the market and give 150M$ price tag to Mbappè, what do you think about that? It’s this situation going to matter on the final price payed to the Monaco?

    Would all potentially top notch stars opt for Real Madrid, as long as they equalled the pay offers elsewhere? If so, should other clubs attempt to bid up the young man’s worth just to deplete Real’s moneybags a bit?

    Would Griezmann, for instance, be a cheaper alternative for ManU/ManC/Chelsea?

    Kane? Sanchez? Lukaku? Much cheaper, I expect.

    • NunyaBusiness

      Griezmann cheaper than what? His own weight in gold?

      None of these players you mentioned will be cheap at all. There is absolutely no way Kane is going anywhere. I actually don’t think Griezmann will go to England, either. Man U and Man City are no better off than Atletico, and Chelsea doesn’t play a good style for him.

      Sanchez to Bayern or Juventus. Lukaku who knows.

    My questions are: what is a goal in Ligue 1 worth these days? Four players with 15+ goals are all PL washouts: Falcao, Gomis, Thauvin and Balotelli.

    The other is how much does Mbappe benefit from how good Monaco’s attack is? Similar to how people were fooled (I wasn’t, but most were) about Memphis Depay because of how good people the team at PSV was at getting him and DeJong shots (and how bad Eredivisie defenses are at stopping them).

    I mean almost 3 goals a game, someone has to get a hatful other than the main striker, right? Might also call this the Raheem Sterling conjecture.

      “Four players with 15+ goals are all PL washouts: Falcao, Gomis, Thauvin and Balotelli.”

      Falcao was recovering from a torn ACL that’s why he was bad in the PL. And he was low on confidence. The fact he scored 2 goals at the Etihad including one beautiful chip over Caballero should suggest you that his scoring record isn’t inflated by the so-called mediocre level of Ligue 1.

      Similar for Balotelli. We all know he has the talent. A few seasons ago he was quite good with City in the PL.

      Thauvin is much better than he was two seasons ago. And he was plaing for an awful Newcastle side. Add to that he didn’t want to leave Marseille in the first place.

      Fair enough Gomis is an average striker who thrives against sub-par oppositions.

      • NunyaBusiness

        I don’t care the excuses. They failed in the Premier League.

        • guguix

          You’re an idiot then.

          • NunyaBusiness

            What, because I don’t go in for sob stories? Balotelli failed because he wasn’t good enough. Falcao had two chances with two big clubs and did the square root of nothing. Thauvin was just terrible, even if he has gotten better it’s unlikely he’d suddenly be good enough.
