So Ozil has pretty much said he is staying at Arsenal. Read somewhere that the contract is pretty much 90% done now, should be finalised when they get back from their tour.
As for Giroud??, there is still a chance he might be sold. Pretty much said in an interview that he has no problem with moving clubs. He just wants more first team football and barring an injury to Lacazette, I can't see him getting much. Although we have plenty of games for him to play ie europa league and the usual cup games.
Sanchez is the main worry though, no sign of him signing a contract. Unless Wenger has something lined up for him.
