Ramsey was missing for almost 4 months.
Ox was missing the first few months.
Wilshere was out an extended time...
Walcott who was our go to scorer when we needed tore his ACL in FA Cup game against Tottenham.
Ozil was out for almost 2 months towards the end.
Sagna is likely on his way out which sucks. The problem with Arsenal is Ozil had to adjust to the physicality of EPL and more games played in a shorter amount of time. Ozil was gassed by December lol. Also, the dream was he and Cazorla were perfect together but that partnership didn't really work out either... I'm hoping Ozil's second year is more productive as he's still learning the league.
Giroud is solid but he no showed against all top sides (Liver, City, Man U, Chels). Giroud can put up numbers on the middle and bottom tier teams, but against top sides with better defenses he struggles. His first touch and holding the ball is decent, it's just he doesn't have the speed or quickness to break through the line without help.
