Out of curiosity, nothing more. Where would he even play?
Midfield is stacked with Fab, Hendo, Wijnaldum, Keita, Ox, Milner. That’s before you even take into account the likes of Minamino, Shaq, Origi and maybe even Jones.
The front 3 isn’t changing. We’ve lost Can from when Coutinho was at the club but I think that’s it, whilst an extra 4 have been signed in the midfield/attack since.
The only player who may possibly leave is Shaqiri, but even then there is very little room for Coutinho. He’d still command a relatively high fee and his wages will still be right up there among the highest.
The only possible way I can see for him coming into the team is if Milner is used purely as a bit part and cover player and another 2 are moved on. Likely Shaqiri and given the contract situation Gini, but Gini is a player I don’t think Klopp would want to sacrifice to make the return happen.
Whether you want him back, don’t want him back or on the fence, there’s not really a place for him in this team.
