I noticed when Caldwell received the ball and went forward, Diame stayed in midfield and eventually when the ball came back he didn’t fall back and was just strolling.
Caldwell managed to get back within five yards of the play by the time the ball went in the net and he had been the highest player up the pitch.
So any number of players could have been back covering. He spotted a chance to out number Chelsea, and i’d rather us be positive because in the long run it will pay off for us.
