5.- Ivan Rakitic
The FC Barcelona midfielder already knows that he is on his way out at the Catalan club. He already had a verbal agreement with Juventus last summer, but the club decided to trash it.
During the next transfer window, the Croatian midfielder might look at the options he has outside of the Spanish La Liga. This is the ideal moment for the Red Devils to get involved in the negotiations. Rakitic still has a good couple of years playing at the highest level left in him.
