1. Franco Di Santo - Wigan Athletic

Di Santo is stalling on signing a new deal - and may let his contract run out to give Roberto Martinez a headache. 

The 23-year-old Argentina international has been an integral part of Wigan’s side, and is their leading marksmen.

Wigan will be desperate to tie their star striker down to a new long-term contract, but Di Santo may have bigger ambitions than fighting for survival each year.

Di Santo would be a good signing for most Premier League clubs because of his adaptability, pace and skill. He is also young and has plenty of potential to develop in the future.
