Bayern Munich general manager Uli Hoeness believes the club face a “brutal struggle” to keep hold of Franck Ribery.

The France winger is the hottest property in the Bundesliga and has been linked with moves to Real Madrid and Manchester City.

“Our goal is to hold on to Franck with all our might,” Hoeness told the Bild newspaper. “But it will be a brutal struggle.

“Enquiries about him will come in. Therefore the most important thing will be that we don’t waver and announce clearly that we are keeping him. Otherwise uncertainty comes in and his agent senses his chance.

“But if we keep our clear position until August 31, when the transfer window closes, then afterwards we can try to extend his contract beyond 2011.”

Hoeness, who leaves his own role with Bayern in the summer, believes Ribery’s agent is keen for his client to move away from the Allianz Arena, even though the Frenchman is settled there.

He added: “He still has a two-year contract here without clauses. And he and his family feel at home here. In my opinion only the lack of hope for an international title can change his mind about a transfer. But I don’t see this lack of hope.

“That his advisors are maybe interested in a transfer, that is clear to me. Advisors earn generally only through transfers, not if a player stays year after year at the same club. And they certainly want to continue to earn. We have to be aware of that.”

Despite a difficult start to the season, Bayern are still in the hunt for both the Bundesliga title and are through to the quarter-finals of the Champions League.

France kept their World Cup qualifying hopes alive when a Franck Ribery goal earned a 1-0 victory in Lithuania on Saturday.

Ribery netted in the 67th minute with a powerful 20-metre drive after being set up by Yoann Gourcuff.

France, who have a game in hand on leaders Serbia, remain third in Group Seven with seven points from four matches.

Les Bleus are two points behind Lithuania, who meet the French again in Paris on Wednesday. Serbia, 3-2 winners in Romania, have 12 points from five games.

“This win is very important for us. We all had a good match, we fought on a bad pitch,” Ribery told the French TV channel TF1.

“We had so many chances and we wanted this goal very badly. Now we have to do it again on Wednesday at the Stade de France.”

Coach Raymond Domenech said: “We dominated and we won but there will be another game in a few days. We should not gloat yet.

France international Franck Ribery has admitted that he is growing tired of all the speculation about his future.

Hardly a week goes by without the player being linked with a move away from the Allianz Arena and all the rumours are starting to annoy him.

He has once again tried to put an end to all the exit talk by telling L’Equipe: “Everyone keeps asking me about my future, they only want to talk about when I will leave.

“But it is useless because I don’t want to talk about it anymore. I am fed up.

“Staying or leaving? I don’t reply to that question anymore. I am enjoying life at Bayern and I feel fine here.”

Frank Ribery was in inspired form as Bayern Munich thrashed Sporting Lisbon 5-0 in Portugal to virtually secure their progression into the Champions League quarter-finals.

A superb first-half solo effort and a second-half penalty by French winger Ribery, plus a second-half double from Italian World Cup-winner Luca Toni, gave Bayern one of their best European nights of recent years.

Having lost to mid-table Cologne on Saturday in the German league, Bayern bounced back in style and coach Jurgen Klinsmann was predictably delighted.

“It was fun to watch after the second goal went in,” he said. “It was impressive the way the boys responded after the defeat by Cologne.”

Although Juventus have allegedly stepped up their chase of French ace Franck Ribery, the Bavarians tactician has insisted that he is confident that his side’s prized asset will remain in Germany.

According to rumours in Italy, Juventus directors are already in the process of drawing up their summer shopping list and Bayern Munich attacking midfielder Franck Ribery is allegedly one of their primary targets.

The Old Lady are scouring the transfer market to find a replacement for Czech dynamo Pavel Nedved, who is set to hang up his boots at the end of the season, and the 25-year-old French international seems to fit the bill.

However, Bayern coach Juergen Klinsmann has reiterated that both the club and the player are unfazed by all the paper talk.

“I am not afraid because I know that Franck is happy at Bayern,” the ex-Inter striker is quoted as saying on Alice.it.

“If other clubs are interested in him, it’s because of how well he is performing with us. He is a unique player, and I am confident that he will remain with us for a long time.”

Ribery joined the Bundesliga champions from Olympique de Marseille in the summer of 2007 for a fee of €25 million.

The French superstar has confirmed that he is not on the verge of joining Real Madrid.

The future of Franck Ribery has been an interesting story over the past twelve months, and despite everything that has happened and all that has been said, he has remained loyal to his current club, Bayern Munich.

The French international has been linked to a number of clubs over time, with the most recent being Real Madrid. These rumours were confirmed by Franz Beckenbauer, who stated that it would be an option if the player himself really wanted to make the move to the Santiago Bernabeu.

In response to these comments, the midfielder has declared that the speculations are untrue, and that he has no intentions of joining the Spanish giants anytime soon.

“I have never thought about leaving Bayern Munich,” Ribery assured in an interview reported by Tuttomercatoweb.

“Real Madrid? These are only rumors and nothing more,” he concluded.

In addition to these latest claims, Juventus may also be lining up a move for the Frenchman, as they see him as an ideal replacement for Pavel Nedved who is set to hang up the boots at the conclusion of the season.

Bayern Munich manager Uli Hoeness has slapped a mammoth €150 million price tag on Franck Ribéry after it was rumoured that Milan were looking to him as a potential replacement for Kaka.

With the crazy fee of €130 million (£120 million) being offered to AC Milan by Manchester City for Brazilian Kaka, Bayern Munich manager Uli Hoeness has issued a firm “hands off” warning regarding Franck Ribéry by stating he would cost €150 million (£140 million).

The Frenchman emerged as a potential target for the Italian side this week as Manchester City tabled their record-smashing bid for Kaka.

Even though the move has seemingly fallen through, Hoeness has spoken of the Bavarian club’s valuation of the winger.

“If Kaka is meant to be worth [€]130 million, then Franck Ribéry is worth [€]150 million,” Hoeness told Eurosport television.

“We would only perhaps start to consider selling him at a sum like this.”
