Chelsea are willing to pay ?21million to land West Ham United's Enner Valencia before the transfer deadline, according to a story in one of this morning's tabloids.

The Sun's Alan Nixon and Dan King claim that Chelsea are willing to offer West Ham the opportunity to make a profit of around ?8million on a player they purchased only six months ago.The Premier League title favourites have already splashed out ?27million to land Fiorentina's Juan Cuadrado this week, but are still keen to land the Ecuador international according to the story.However any such overtures are likely to be rejected by the Hammers, with David Sullivan insisting only two weeks ago that none of Sam Allardyce's first team squad were up for sale.Valencia's career at the Boleyn has been hit and miss so far. Whilst he hit the ground running with technically excellent goals against Hull and Stoke, he has struggled to maintain a place in Sam Allardyce's first team with Andy Carroll and Diafra Sakho ahead in the pecking order of late.Valencia, who cost West Ham circa ?12.5million when signing from Pachuca last summer has thus far scored just four goals in his 23 appearances for the Hammers. The current record transfer fee received by West Ham for a player was the ?18million Leeds paid for Rio Ferdinand 15 years ago.
