6) Kevin De Bruyne (Wolfsburg)
The former Chelsea star has been among the best midfield players on the continent so far this season. His performances have inspired his side to second place in the Bundesliga, and brought him to the attention of a number of major clubs.
5) Radamel Falcao (AS Monaco)
Madrid have asked after the Colombian hit-man in the past, and with United looking unlikely to take up the chance of buying him permanently, he could well be available next summer.
