He was decent against Arsenal, and improved after a poor start against cluj. I don't think it's helped him find rhythm being in and out of the team and recently coming in to quite unbalanced teams. But at the same time I think some of his problems are due to his own lack of all-roundedness to his game. He seems like he can thrive in quick, high tempo games where he can push up the pitch but seems to struggle in slower tempo games.
You can blame midfield partners only so much, the top midfielders are able to influence games without always needing the perfect partner and I think clevs problem is his game is quite heavily focussed on short quick passes, but at the moment he lacks a cutting edge to his game to play higher up the pitch for us. When he has to play a deeper role such as against cluj he can struggle to impose himself. He doesn't have the power that Ando has to be able to pick the ball up and carry it, nor seemingly the same long range, so if the link man ahead isn't there, he can struggle.
But like I said he's not been helped by being in and out of the team and our general mixing and matching of teams/players at the moment. We've not really got into a rhythm as a team and so that impacts on everyone. Hopefully he can soon get a run in the team because at some point we're gonna need to settle on a first choice midfield, particularly now we're approaching a vital part of the season and with preparation for the CL knockout stage.
