Crystal Palace chairman Steve Parish has revealed that his side have rejected Tottenham Hotspur's approach in signing Wilfried Zaha and issued a warning to the north London club that the attacker is not for sale in this transfer window.

The 23-year-old rejoined the Eagles after a disappointing spell at Manchester United, where he was Sir Alex Ferguson's last signing at Old Trafford. According to the Daily Mail, the winger informed his manager Alan Pardew that he is looking to complete a switch to White Hart Lane.

Tottenham manager Mauricio Pochettino believes Zaha has got the potentials to be as good as United legend and Real Madrid star Cristiano Ronaldo. Parish confirmed that the London outfit placed a £12m ($15.8m) bid for their star player.

Palace's chairman has assured fans of the club that Zaha will remain at Selhurst Park beyond the summer transfer window.

"We had a bid from Spurs but £12m – it's ridiculous. I can't imagine that they're serious," Parish told talkSPORT, as quoted by the Express.

"There is no chance whatsoever of Wilfried Zaha leaving the club in this transfer window. I can absolutely reassure every Palace fan he is an integral part of our plans. We've told Spurs that there is really no point bidding for him because he is going nowhere - 100 percent guaranteed.

"It's not right really that players get their heads turned. I was told that the manager there thinks he's the next Ronaldo. Well I'd like to get the next Ronaldo for £12m," he added.

"I haven't spoken to the player. The manager and the player might have had a conversation but I'm chairman of the football club. I decide who leaves and he's not leaving. He'll have to get his head around that.

"It is difficult for Wilfried because a big club have come in for him, but we want to finish ahead of these clubs. We need to convince Wilfried that he can achieve what he wants here and that conversation will happen once the transfer window is closed," the Palace chairman said.
