WEST HAM are on red alert as French giants Lyon prepare to sell striker Moussa Dembele.

Hammers boss David Moyes is a big fan of the former Celtic striker, who is frustrated with being left on the bench recently.

However, the price on Dembele’s head will still be a problem for any Premier League suitors, which also include Manchester United.

Lyon could be persuaded by a bid from about £30million but which goes higher with bonuses.

West Ham have money to spend after the last window, when they failed to buy a new frontman.
