With Nemanja Matic's services now officially secured, Jose Mourinho's attempt to create a title-winning side at Manchester United has taken a significant step closer to completion.

The Serbian international is the final ingredient needed in an incredibly exciting engine room, also containing a real terrier in Ander Herrera and the most expensive player in the world in the form of Paul Pogba.

Looking at the rest of the starting XI, there are two possible gaps that still need to be filled; an attacking midfielder or a winger who gives United creativity and pace, and a left-back.

Mourinho already has some options there, namely Matteo Darmian, Daley Blind and Luke Shaw. But all three were in and out of the side last season, so the question of who should be United's first choice No.3 remains open to debate.

Would you pick the 6 foot Darmian, the England international, the Dutch utility man or make a new signing for the position before the transfer window slams shut? Let us know by voting below...
