3) Robin van Persie (Manchester United)
A risky signing from Arsenal, Robin van Persie cost around £24m when he was approaching 30 and had a bad record with injuries. It is now said he would go for just £11m this summer.
4) Nani (Manchester United)
Signed for close to £20m, Nani started brightly but faded at Manchester United and is now surely set to leave this summer, with £10m a realistic fee for the Portuguese flop.
