Ibrahimovic will have a decent season, and will get 15-20, I expect. He'll be lead striker, and if Utd have any way of getting the ball to him, he's big, pretty good in the air and can shoot.
Mkhitiryan looks a decent choice to give the midfield some craft and drive after approx. zilch last season.
Bailly is a bit of a punt - will be struggle or take to it will? Will be punch Smalling out for being clueless?
They also have Shaw back, which is almost like a new transfer.
Pogba still looks very raw to me, and how he deals with not retaliating after being clogged may define how well he gets on.
Top 4 for certain, and I expect top 3.
How Mourinho treats the mass of midfielders will be interesting - Carrick's a bit part player now, but Schneiderlin will want to play, Fellaini will want to assault people, Young will want to fall over a lot.
At least Bruce has gone, so one less 6-point gift club, although Moyes will still grovel at their feet presumably.
