At the game I thought Welbeck was fouled just before Aleti's goal. Just watched the replay for the first time on tv and I still think it was a foul on Welbeck and I think he actually played well in the first leg. Yes he missed a chance but he wasn't the only one.

I fear Henrikh is no more likely to be a direct goal threat than Wlebeck is and Welbeck is good in the build up play too. I don't think the choice (if one needs to be taken between them) is a actually a clear cut one.
