Manchester United and Chelsea have made offers for the Bayern Munich winger Franck Ribery.

Karl-Heinz Rummenigge, the German club's chairman, says Barcelona have also made a bid but there has been no movement from Real Madrid.

United have targeted the France player as a replacement for Cristiano Ronaldo, who will complete a world-record £80 million move to Madrid this summer.

It was thought initially that they may be beaten to his signature by Real, who have also agreed to buy Kaka for £56 million. Yet Rummenigge insists only three clubs have made an approach for the 26-year-old.

"We are relaxed and proud that we have one of the best three players in the world under contract," he said.

"Real Madrid president Florentino Perez and his advisor Pedro Jimenez asked if we were willing to speak with them over a transfer but we rejected the chance and we have no intention of selling Ribery."

Asked if Madrid made an offer, he replied: "No but other clubs have done. Chelsea have lodged a bid, as have Manchester United and Barcelona.

"We are completely relaxed about it. The power lies with Bayern Munich."

Bayern have repeatedly insisted Ribery is not for sale and Rummenigge is adamant that the club will not relent and cash in on their prize asset, believed to be worth £40 million.

"I don't want to talk about sums of money because it is not in our interest," he added. "The amount is irrelevant.

"There is always going to be the perception that Bayern Munich are trying to push the price up and that there is a certain value at which we'll have to accept, but I'll say it again: we want to keep Ribery.

"A player has to respect his contract, in his case until 2011. He is on holiday now and then we want to have a successful season with Franck next year."

Despite the huge profit Bayern could make from selling Ribery - they bought him from Marseille two years ago for 25 million Euro - Rummenigge is worried about the inflated sums being spent this summer.

"It makes me concerned for the future," he said. "These amounts would not be possible in Germany due to the license agreements but in Spain the rules are different.

"I have already arranged a meeting with Michel Platini [the Uefa president] to discuss the matter. We need to have new rules regarding financial fair play."
