Welbeck in 71 minutes did nothing except break up our attacks
Nani in 30 odd mins set up the winning goal
Yeah perhaps he should have started.
The corner was the only thing Nani did good, yes that may be 1 more thing than what Welbeck did but lets not fool ourselves Nani was quite possibly even worse than he was against Everton when he came on
EDIT: It's also worth pointing out the 2 or 3 totally amateur corners Nani put in before that one as well
