West Ham United risk losing star midfielder Momo Diame due to an escape clause in his current deal.

The Daily Mail says talks are expected this week with the players' agent but the free transfer signing from Wigan appears in no rush to sign a new deal.

In order to lure him to West Ham in the summer, the club were forced to agree a 'trigger clause' in his contract. The size of the clause is a closely-guarded secret at Upton Park, but rival clubs are circling and prepared to pay around £6million.
