Assuming we sign Kante...
From our midfield, I would sell Fellaini and I would buy Pjanic as playmaker.
Kante and Pjanic are available and they are not too expensive.
I would just add Zlatan for free and buy a player like James, Mahrez, Sane or Mkhitaryan.
Pjanic reminds a bit of a more mobile version of Fabregas.
Everyone knows that both of them are great on the ball, passing game is running through their veins.
In my view Pjanic is more lethal in front of goal
(when does Fabregas ever shoot apart from free kicks these days) but i question Pjanic's work rate.
Speaking of fulfilling his defensive duties and whether or not he's able to close down the pitch
when it really matters.
I don't want to see another liabilty off the ball here, the league has its demands so i remain sceptical.
We've already got Shaw as a good attacking threat, the resurrection of Schneiderlin is possible under Jose Mourinho (imo) and according to your post we're assuming that we've already snapped up Kanté.
So what i want to see is (more) soldiers. High pressing game and good attacking play.
Schneiderlin and Kanté running down the pitch and dispossessing opponents time and time again would be a great. To complement a possible 3 men midfield i'd much rather have someone like your mentioned Mkhitaryan who is all over the pitch.
Mahrez is the current 'player of the league', every team in the country would love to field him.
Sané is a good prospect, but if we were to get him, maybe Memphis's time would be up.
i think Sané is a bit too pricy for what he has to offer, but as Rio said, footie is a game of opinions.
James is great number 10, but after Özil and Di Maria i think Real will demand about 65 mil pounds and i'm not sold on paying that much for him.
Yes, i've seen parts of the current Copa America and the boy is getting back to his best.
Zlatan would fit in nicely at United, with Mourinho at his side, both of them would demand trophies and goals, it doesn't get any better than this.
