West Ham are ready to bid big for Bournemouth striker Callum Wilson.

The Sun says the Hammers are poised to make an offer worth up to £25m for Wilson.

It comes as it was confirmed striker Diafra Sakho will miss up to six weeks with the thigh injury he sustained against Manchester United.

Hammers boss Slaven Bilic wants Wilson as his main January transfer window priority after a poor start to the season.

It has left West Ham just one point clear of the relegation zone after more than a third of the season gone.
