3) Edinson Cavani (replacing Javier Hernandez)
With Javier Hernandez on the way out, United do have room in their squad for another striker. Quite how Louis van Gaal would be able to keep Cavani, Wayne Rooney, Robin van Persie and Danny Welbeck all happy with their levels of first team football is anyone’s guess – but there is little denying that it is an extremely desirable situation to find yourself in, and one that many Premier League clubs can only dream of. The Uruguayan forward has been linked with a move away from PSG this summer, where he has reportedly grown frustrated at playing second fiddle to Zlatan Ibrahimovic.
