#3 Pablo Maffeo (Girona, on-loan from Manchester City)
Loaned out to La Liga side Girona, Pablo Maffeo is a Manchester City player and a promising youngster who also boasts versatility, just like the aforementioned Fosu-Mensah.
Usually operating as a right-back but equally capable of playing further forward on the wing, the 20-year-old has been at City since joining their academy for a reported £90,000 from Espanyol in the summer of 2013.
After a few encouraging performances for City's first-team last term, he really came into the fore recently after successfully man-marking both Cristiano Ronaldo and Lionel Messi in domestic fixtures this season.
He has the potential to be a very good player, one that Pep Guardiola could rely upon in future, but it'll be interesting to see whether his compatriot will grant him first-team opportunities next season with squad depth an ever-increasing headache for the league leaders to consider.
