4) Joao Moutinho (AS Monaco)
The 28-year-old surprised plenty of people when he followed Radamel Falcao to Monaco in 2013. Could he also follow him to Old Trafford?
3) Miralem Pjanic (AS Roma)
Roma’s star midfielder over the last couple of the seasons. The Bosnian has lots of quality and would definitely add something to the midfield.
