He's a striker and he's been playing a far too supportive role, i'd expect in his position to be there waiting for the ball with Rooney or Carrol.
when he has he's flopped every chance, Carrol should be our man for the first half he's solid he's eager and plays his heart out making chances and applying the pressure.
Welbeck is in my opinion better played in the 2nd half to replace Carroll or Rooney
