We'll see about that next week when Mourinho rips him a new one.
I'm not a manager, not even football coach but I know perfectly well how to play against Wenger's Arsenal. It's way too simple actually. Pull back everyone, strengthen the sides, tell defenders to watch for cute little crosses (Jack Wilshere, master of passing into nothing hopping that teammates read his mind), wait for their overconfident midfielders lose the ball (they wouldn't lose it in any other League because ref would call a foul, but in England you can play rugby from time to time), then counterattack and go against slow as fuck Mert. Simple as that and works every time. Because fucking Arsenal always play the same! Do you remember when Arsenal was godlike tier and no one could defend against them? Well one game something happened, some manager figured it out and placed proper defense against Wenger's time for the first time in years and it worked. Since then magic was gone and Arsenal started struggling. Until this very day. Soon there will be 10 year anniversary of that moment when Wenger's tactics became publicly known to every manager in England.
If Wenger tries to go for win against Chelski, which he will do because there is no other choice and frankly, Arsenal can't defend. He will be humiliated, again. Mourinho will place that einstein jugend on one wing and Hazzard on the other and they will mess the Arsenal on counterattacks so bad, Jack will be so pissed he'll do something overly stupid and get a loong suspension. Rest will just be sulking around the pitch for last 60 minutes, after they conceded 5 goals in just 30 mins.
It doesn't take a rocket scientist to figure that out, every single football aficionado knows this very well.
