It kinda does, since our poor run in the league where we gave away the league happened while he was out.
Why flick wanted a top class winger this summer
It 100% doesn't simply cause sample size is way too small to draw those conclusions.
Our poor run also included 2 losses where he played(against Leganes he was taken off minute 75)
In the games where he was completely absent we lost 2 games and drew 1. The Celta game where we gave away 2 goal lead in minute 84 after one of our players caught an unnecessary red.
He also missed 1 game in CL and 1 in Copa del Rey which we both one. Tbf Copa was against very poor competition. But one of games we lost was against atletico where we gave away 1 goal lead which is a stronger side.
If the argument is he is an important player for us? Yes. No one will dispute that. But way too early to draw parallels to messipendencenia. This team looks more balanced.
