You're right, they shouldn't. It's not like they were violent and it's a valid argument. And it's not being anti-Semitic either.
Don't think they have enough depth in defence. I think they need a starting left back so that Azpilicueta can move to the right, and another center back to slot in next to Zouma once he's back from injury. Also Conte likes to play with 2 strikers but he has to play with just 1 at the moment since they only have 3 in the team. So one more strikers is needed I'd say.Already dismissing Chelsea?
Arsenal got lucky. Leicester should've had a penalty (maybe two) and Coquelin shouldæ've been off with a 2nd yellow. Leicester also created the bigger chances.
