Too easy for Benteke to score, and it was Ramires who gave the ball away which lead to the goal. And, whilst not inherently violent, Ramires needs to learn how control himself. He is capable of some absolutely brilliant things, but too much of the time he just looks lost on the pitch, and around other players.
And I would get Torres on. I know we have the Europa League to worry about, but at least Torres runs around, even if he doesn't score. Ba just seems to meander through the defensive line, whereas Torres can create space for Mata/Hazard.
