4. Karim Benzema (Real Madrid)
The talented French striker has been linked with Manchester United before while he was a young player at Lyon, and has shown himself to be a world class finisher in his time at Real Madrid. However, the 25-year-old has had a slightly harder time at the Bernebeu this season, finding himself falling down the pecking order under Jose Mourinho. Benzema has reportedly been identified by Moyes as a target, and could find a new challenge a useful step in his career. Also able to play out wide, the France international would be a useful addition to a United squad that is in need of several changes both upfront and in the attacking midfield positions.
Benzema could certainly do a good job as a Rooney replacement, and also do a better job of providing assists from the flanks than the likes of Nani and Ashley Young have managed this season. Despite a poor year by his standards, he has 19 goals and 20 assists in all competitions – just imagine what he can do when he gets back to his best.
