Player Valuation: £70m
If 3-4-3 is the case then players likes of Allan, Alli, Doucoure, Gbamin and Davies will all be surplus to requirements, none capable of playing in a 2. Iwobi will be permanent RWB, to me that is a massive waste.
The team that plays 2 in CM well is Spurs with Hojberg and Bentancur, both big, physical, mobile and they can play a bit. We have no one like that nor are we likely to be able to afford players like that.
There's an argument that all of those players aren't up to it in any formation though
The formation is not the major issue, it is, and has been for a long-time the players. Our midfield has been shocking for years. If you have the playerts for it, 343 or 352 is fine. If we plan on playing that as a base tactic next season, then in the summer we have to get rid of those who can't kick a ball.
Gomes - crap
Allan - cant run.
Delph - on a free
Davies - crap
Doucoure - can run, but cant control a ball.
Alli - could potentially play off the striker but in a 2man midfield, no.
I'd get rid of 5 out of 7 personally. I think its fairly obvious which 5 as well.
