Judging by this season alone, we have very clear positional targets:
Right Back - Coleman, Kenny, Holgate, Godfrey and even Iwobi to an extent, have stepped in this season which has made it quite clear we are looking to strengthen here as although each player has adapted neither has really made this position undropable.
Coleman will remain as backup next season, Kenny will return from Celtic for one last chance to make this spot his own but we seemed happy to sell to Burnley in January so maybe not. Godfrey and Holgate will want to be pushing Mina and Keane for their spots and Iwobi will be trying to claim his right winger spot.
Right Winger - A position held by James during the earliest part of the season but he now has been used as a more free role becoming more central to the play. Iwobi has been used with real purpose especially v Wolves but he too has been staggered in this role. Even Richarlison has been pushed over on occasion.
Walcott's loan out to Southampton left a more experienced player to fill into this role but honestly he was very pleased to be moved on.
Second Striker - While DCL has been a revelation this season, he has found some games tough and even needed a rest to get back into the goals The addition of Josh King is a direct swap for Tosun which already feels like an upgrade. We also have Kean to return from PSG but with his current form at the French club, I think he'll be looking to be more than 2nd fiddle
Whether King is willing to make his move permanent and whether the club is willing to spend a small fee but huge wages on a bit part player at 29.
I know a lot of people will bring up the Goalkeeper situation but I think Carlo is happy to have a rotation of keepers and the club seem happy with Olsen so far so I'm expecting this to be a permanent position in the summer
