Think the squad needs 5 to challenge for everything I think.
CB
LB
DM
CM
RW
The two extra midfielders will strengthen the pool. Even if Fred and McTominay were replaced in the XI, they are great back ups to have. Add in Pereira and the younger ones like Garner, then that should provide decent MF cover, at least until we are ready to go again in the market.
A RW as it stands will take the attacking pool to 5 for 3 spots. Ideally we’d have 6, but Sanchez will be back and we probably won’t be able to shift him so he can probably be the 6th.
CB is needed as I don’t think Lindelöf is real top class, and I don’t think we have any coming through with that level of potential. It’s not urgent, but eventually, for a title winning side, we will want better.
Our LBs of course are not good enough.
