I feel Welbeck had the chance to change the game, but he did not take it. The first instance was not his fault, as he did well to lay the ball of to Wilshere, but Wilshere fail to capitalize on that golden opportunity. The second instance was the backheel he tried in the box. It was just a poor attempt and showed that he does not care about whether he scores alot of goal or not. Costa or most clinical strikers would have just turned around and have a go at the keeper without trying the fancy trick.
Welbeck is a strange player. He definetly has the ability and on another day, he would have had a higher rating if he had been more decisive and lucky, but it is now becoming a consistent theme rather than a luck factor when he spurns these chances. The Bayern game and the city game where he tried a failed chip attempt shows this consistent theme of failing to capitalize on chances he should have done better in if he was not so concerned about the aesthetic beauty of his goal. He needs a manager that has the fear factor. Van Gaal would have been a good manager for Welbeck, because he would not put up with his lack of indecision. It is shame he left United as I feel, a Rooney-Welbeck/Falcao combo uptop would have had us near the top of the league
