I think Klopp wants the Villarreal level of performance every week.
Theirs no way you can get that level of performance, the running and pressing, with the same 11 players every week.
Coutinho isn't playing as a number 10, neither is Lallana. I think they'll stay as wide players, he'll bring Gotze in to compete with Firmino and he'll bring another wide player in too.
Hopefully we're playing RealMadrid on a Tuesday next season then playing Arsenal on the Saturday to stay top of the table. We'll need loads of good players for that
