Allardyce Tried To Sell Martins!
Keegan: "I haven't received a bid for Martins, no, but I want to keep all my players and add to them if I can.
"Anyone that goes will be a bit of a blow, especially if something like that happens late on in the summer.
"However, Arsenal have definitely not approached me."
Glenn Roeder paid £10m for Martins in the summer of 2006, but United managed to do a deal with Inter Milan that saw the transfer fee spread over five seasons. As a result they still owe £6m for him.
Sam Allardyce contacted Martins' agent at the end of last July and told him United were prepared to unload the Nigerian international, but there were no takers at the time.
