He's no less consistent than a few other more experienced players, who the majority on here champion and have championed previously. The constant chopping and changing in the side (and injuries) have helped no one. When have we really had a settled backline, midfield or attack this year? He's covered for Salah, he's played ahead of a defensively awful right back and he's been dropped to the bench more often than not for Szobo who has been just as frustrating and up and down form wise.
Next season is a big one for him, he has all the attributes to play that central role, he just needs a consistent run and a bit more belief to try things in the final third. It'll be interesting to see what Slot does with those players who haven't really found their "best" role under Klopp - Trent, Elliott, Gapko, etc.
