I would bring Benteke back in and drop Weimann to the bench. Although he tired in the 2nd half, I would start with Cole in the first half and take the game to them. I would try and get Gabby to put everything into the first half and then replace him with Weimann and replace Cole early in the 2nd half with Richardson. If this was a game plan from the start, they ought to be able to take the game to them again in second half.
If we are going to get anything out of the game, we have to play on the front foot and get out of this habit of conceding ground and letting the opposition have so much of the ball as the game goes on.
