If he gets the games and stays on form i reckon Osman will fourish, he's always in good areas for rebounds and leaps like the proverbial salmon. Regardless it will be a midfielder and not a striker, this is not a lack of faith in our strikers just the way we are set up. Id be happy if they all scored 10 and no more as long as were scoring
Vellios, he has already made an impact, and from what we have seen he is great in the air, i think towards the middle of the season you will see Moyes become abit more positive and start him.
