I'm not sure if we'll challenge for the title (top 4 is immediate priority), it's still very early, but there are reasons to be positive.
Rooney is hopefully now a peripheral player.
We thrashed Leicester, and we were very good for the most part against Stoke, creating loads of chances, just failing to put them away.
Don't forget, we still have Mkhitaryan to come in and hopefully find some form, he's an excellent player and could easily be our best attacker.
There are plenty of concerns, as ever. I think Mourinho's treatment of Schweinsteiger is stupid - whatever he may have done wrong (being in Germany too much etc) - and Schneiderlin is clearly a very good player who doesn't seem to have a place either.
