West Ham United have made a bid for Leeds United captain Ross McCormack, Sky Sports understands.
The Scotland international is the top scorer in the Championship with 18 goals to his name already.
McCormack signed a new long-term deal last summer, when Leeds fended off multiple bids from rivals Middlesbrough for the the 27-year-old.
Now Sam Allardyce's Hammers, who are desperate to bolster their squad as they battle to avoid relegation, have launched a move to try and lure McCormack to Upton Park.
McCormack has just been made captain at Elland Road by manager Brian McDermott, who will not want to lose his star striker.
But West Ham are confident that they can prise McCormack away as they look to complete at least three deals before the transfer window closes next Friday.
