Man Utd Transfers: 10 Players They Must Sign To Topple Man City

The ship may have already sailed on Antoine Griezmann, the Atletico Madrid man now said to be closing in on a move to La Liga rivals Barcelona.

But until the deal is signed, sealed and delivered, there's still a chance that he could think better of spending the next few seasons in Lionel Messi's shadow and instead decide to line up alongside Phil Jones and Marouane Fellaini (yeah, it's a long shot).

There are few better footballers on the market this summer than the 27-year-old Frenchman, who has grown into one of Europe's leading marksmen under the tutelage of Diego Simeone since joining from Real Sociedad in 2014.

With Lukaku and Sanchez already on the Old Trafford books, strengthening the front-line isn't a top priority for the Red Devils, but genuine difference makers are exceedingly hard to come by. They'd be foolish not to at least try for one more.
