6) William Carvalho to Manchester United
Despite long-standing interest from Arsenal and Chelsea, it looks increasingly likely now that Manchester United could be set to complete the signing of Sporting Lisbon defensive midfielder William Carvalho. With moves for bigger names such as Arturo Vidal and Toni Kroos failing this summer, Louis van Gaal has now turned his attention towards the immensely talented Portuguese international, who is widely regarded as one of the most promising young players in Europe and who would certainly make a fine addition to this United midfield.
