If you want to go with stats then McGinn has only 4 assists in 2016, that is very poor for a wide player. We all know Rooney limitations outside the box but you can't ignore a 1 goal in 2 games (includes subs appearances).
Yes i'm wrong saying he's very average player but he's not the wonder player some are making out and as a wide player hasn't had a good 2016 in terms of assists although scored a few (I Don't think he is good enough to be a striker upfront alone)
