I don't understand Chelsea at all. Great for us that they've agreed to take Sancho (I think?) but how does it help them to sign a player in a position they were so stacked in already that they literally have banished a very high-profile senior player from the first team who plays the same positions? Mayyyybe they get Sancho back to decent form and make a profit on him in a few years, but he has to play a lot of football to do that, which means if they do, one of the other high-profile wingers they've bought to develop and make a profit on will suffer.
Chelsea's current wingers:
- Pedro Neto
- Mykhialo Mudryk
- Cole Palmer
- Noni Madueke
- Christopher Nkunku
- Jadon Sancho
- Joao Felix
Now you could maybe argue that a few of those can play as a #10, but from what I can tell Maresca wants to play a classic 4-3-3, which means you have 7 players for two positions, with a couple of them maybe able to deputise as a false #9. There's also no clear hierarchy aside from Palmer. None of those players seem to me that they would accept being squad players.
Make it make sense.
