I was one of his critics (not because of the excellent football) but his attitude on the pitch and getting involved in shit every single game. His goal scoring ratio was insane, he could make a goal out of nothing plus he basically almost never missed sitters. In out last two title wins he was in both a top five performer. Morata started great but lately spending more time on the grass than on his feet is seriously pissing me off. Hasn't scored since December in his last nine games, managed three yellows and a red card. I understand that it is his first season, same stands for Bakayoko, Rudiger etc. I will give them all a chance, but overall in this system think Costa was a perfect fit.
