He's really stepped up his game and his comments earlier were interesting about how he didn't think we could get a manager as good as Rafa, maybe he's motivated and thinks we could actually be worth playing for.
When Rafa first signed people were saying that he was more tactical then a motivator, while that's true, the way the team has seemingly given a shit recently, and people like Tiote's performances, tells me that he is actually a really good motivator.
