I respect Boehly's willingness to think differently about how certain parts of the football world work and try some unusual things like buying a player a year early.
The part I'm skeptical about is his overall understanding of the game itself and how you build a team. He seems to approach football a lot like baseball. In baseball, the game is really a series of individual actions and matchups so aside from a few minor things (like having a mix of left and right handed hitters and pitchers) it just doesn't really matter what style of players you have or how they fit together. You just want the best individual players. That seems to be how he is thinking about football too. Somebody handed him a list of who they thought were the best players and he has just been trying to sign as many of them as possible. Its a very different approach to how clubs like City, Liverpool, Spurs, and Arsenal have been recruiting (and I think United is starting to go in this direction too under ETH). These other sides are all about finding players with the specific qualities to fit a particular style of play and being increasingly selective in who they sign.
Nkunku is really a second striker. He has played the 9 but that doesn't seem to get the best out of him - he has always been better playing off a bigger box striker like Silva or Poulsen. He has played on the wing but he doesn't have the burst, dribbling ability, or buildup contribution to really shine there. He's a lot like Havertz, but with less of an overall game and more goal scoring ability.
A 3-4-2-1 system like Potter's can accommodate these kinds of players as long as somebody else is at the tip of spear and you have the wingbacks to occupy the outside channels. But you can only play two of them and Chelsea already have Havertz, Mount, Gallagher, Sterling, Pulisic, and Ziyech for those two spots. They clearly plan to move some of those players on but its an odd choice to preemptively strengthen in that area.
