2) William Carvalho (Sporting Lisbon)
An exciting young talent emerging in Portuguese football, United could be ready to pay the release clause of Sporting Lisbon midfielder William Carvalho, who would cost around £37.5m. The 22-year-old is another fine all-rounder in the middle of the park, and United will hope to beat off competition from the likes of Chelsea for his signature this summer. With Jose Mourinho now stating that his work in the transfer market was done, United could be favourites to win the race for this excellent young midfielder.
