West Ham United co-owner David Sullivan has warned Newcastle United that they could lose striker Demba Ba for just £3m in the summer.
Sullivan saw the Senegal centre-forward leave his club at the end of last season on a free transfer.
Now he has predicted that the Magpies could lose the 26-year-old for a slice of his actual valuation.
"I'm told he's got a £7m get-out at Newcastle and he gets half the money over that," Sullivan told www.westhamtillidie.com. "They keep denying it, but I think you'll see in the summer he will leave Newcastle, or he'll get a monstrous rise to stay there.
"If they get about £4m, half will go to him, so if they sell him for £7m, they'll only net about three because they paid his agent £2m to get him out of here.
"Getting £3m is not bad, but for a player of his quality, it's not fantastic."
Ba has scored 16 league goals for Newcastle this season.
