Behave. Your posts make me want to slit my wrists. Stop catastrophising for 5 minutes because it's genuinely not benefiting anyone.
Cazorla is a solid midfielder, but virtually everyone has some obsession at any random point in the year about players that are injured that if fit would magically make us title condenders.
I'm gonna make this abruptly clear for you, Cazorla is not a world class midfielder that dominates games and single handedly wins matches. He has had just as many poor games and mistakes as any other player in the midfield, and has been part of tons of lineups that have been utterly dominated.
If he was fit and Xhaka was injured, the you would be going on and on and on and fucking on about how the midfield sucks and how the season is over.
Christ almighty get over it and move on. The season isn't over.
