#3 Adrien Rabiot (Free agent)
There is an awful lot of work to be done in the transfer market at United this summer, and they need improvements all over the pitch. Because of this, it may be useful if they are able to bring in a couple of bargains, and there may be no better bargain than bringing in Adrien Rabiot on a free transfer. The French midfielder is currently without a club, after leaving PSG at the end of last season, having been with the Ligue 1 giants since 2010.
The 24-year-old is one of the most sought-after players in European football at this moment in time, and has attracted interest from Spain and Italy, as well as England. He is a very different player to Pogba, but he has the ability to dictate play in midfield, and could be someone who really helps get the best out the players around him.
