Still won't prove anything, since it's different games. As much as no one knows if the others would have scored Ibra's goals if given a chance. The same goes the opposite - no one can know how much Ibra could score in these "suspension games".
Hopefully they'll be able to score, because it will be needed to be able to win the Europa League. Not fair on Ibra to carry the team on his shoulders all the time. He has to be able to "fail" in some matches. But I have a feeling Mkhi will score at least 2 goals in these coming 3 games, just as long as Mata plays too, cause those two understand each really well.
Let's hope for the best, but at the same time, not forget that whatever their performance without Ibra, he's still one of the most important in the team.
