Manchester United are in contention to win a quadruple which is the Premier League, FA Cup and Europa League which they will try to add to the Carabao Cup they won over the weekend.
They still may have a chance to win all four competitions, but it's highly unlikely. At least I don't think that they have what it takes to win the title in the Premier League. I think that the biggest fight for the title will be between Arsenal and Man. City.
As for the FA cup, if they win today against West Ham, they will face Blackburn in the next round so that title is still pretty much in place.
Manchester city is good and capable to winning both English FA and EPL,since they are second on the table and might just overtake Arsenal,if Arsenal loss any of their game. Manchester united will win tonight's match against West Ham because they will be playing at old Trafford, which is hard for them to be defeated at home. It will be an interesting match and I hope it doesn't end up a draw.
