Barkley is actually terrible. He has even more red flags than Lukaku had. For every good piece of play he does 10 awful things. I was actually really hoping Chelsea would sign him (as I was with Lukaku).
We need to be aiming higher - It's not just a backup for Pogba, I think Periera would have been viable for that role - We need creative options anywhere we can get them or even just someone who can drive the team forward. We wouldn't miss him nearly as much with a genuinely talented #10. Lingard is functional but nothing more and Mkhi looks like he was compromised by the aliens in Space Jam.
Ozil, Goretzka, Savic, Pjanic, Fekir - Not necessarily those individuals but we're crying out for creative players of that quality. It's not a problem isolated to any one position.
