Jury is still out on Sessegnon, but I would be shocked and unhappy if we sold him at this point. He's still young, finally starting to perform and our current system is a great fit for him. As is our current manager. I would be entirely unsurprised if he ended up being seen as first choice within 6-12 months.
-We still don't know if the long term plan is a midfield two or a midfield three. Or possibly a mix of both. Either way, way too early to conclude on how many midfielders we need.
-We should only consider selling Davies if we have two other trusted left sided centre backs. We currently have none other than him.
As a general point, Conte has a good track record of making some previously average, inconsistent or just uninspiring players important parts of his teams. His style of play, his methods, or works really well for some players. Some patience to see how that pans out, particularly when players are already doing well under him shouldn't be too much to ask.
