Brentford are reportedly preparing a significant £40m bid to test West Ham's resolve over El Hadji Malick Diouf, according to EPL Index.

The Bees are said to be readying serious financial muscle behind the move rather than a speculative approach, suggesting they see Diouf as a genuine priority target this window. The figure quoted would represent a major outlay for Brentford, underlining how highly they rate the player.

West Ham's stance on any potential offer has not been detailed, and it remains to be seen whether the Hammers would be willing to sanction a sale at that price. As it stands, this is being reported as interest from Brentford's side rather than a confirmed agreement, with the report suggesting talks or a formal offer could follow.

More details are expected to emerge on how West Ham respond and whether Brentford follow through with the reported £40m proposal.
