Skysports.com understands that West Ham have made a bid for Leeds star Max Gradel.
The Ivory Coast international has just one year left on his Leeds contract and has attracted interest from a host of clubs this summer.
But relegated West Ham appear to be the first to have made a move for the 23-year-old forward, putting an offer in to their new Championship rivals.
Gradel has just enjoyed the best season of his career and was named player of the year at Leeds.
After helping the Elland Road outfit to promotion from League One in 2009/10 they narrowly missed out on the Championship play-offs last term, with Gradel scoring 18 goals in 41 league games.
Gradel first came to England with Leicester in 2006 before joining Leeds in October 2009, initially on loan.
