Even a blind man can see that we lack a connection between midfield and forwards. It's so damn obvious. We need far to much time to change from defense-mode to attack and allow Milan to regroup after we capture the ball.
He's had some excellent 90 minute games this season so don't come with that crap and he can definitely go for an hour so why not start him? If he's not playing well or gets tired then sub him, if not keep him on.
