I gotta say this winter window is a masterstroke by Wenger. Arsenal looked deep in **** with so many players having short contracts and probably wondering about their future a different clubs. I thought by the summer club will be in serious trouble, but they managed to turn it around and actually significantly strengthen the squad, and make a real statement about the future. Ozil-Miki-Lacazette-Aube front 4 is as good as any attacking formation in the league.
But then again, losing their 2 highest productive offensive players in the middle of the season, and having to integrate two new talents, no matter how good their are, during a brutal top 4 campaign, sounds like a nightmare waiting to happen.
