West Ham United boss Sam Allardyce wants Momo Diame to step up his game with the winter market now shut.

Allardyce expects the 24-year-old to hit top gear with his future now settled.

He said: "Diame has now got to continue his growth as a player. He must continue extracting more and more out of his game because there's still a lot more to come. He's got to get better than he already is."
