Manchester City target Dzeko wants switch

Wolfsburg's star striker Edin Dzeko has once again reiterated his desire to leave the Bundesliga outfit ahead of the new season.

The Bosnia international is thought to be on Manchester City's shopping list and he is hopeful of moving on to further his career on the continent.

Speaking to German newspaper Kicker, he said: "I want to clarify that it is not a matter of money, but of ambition. I feel I have to take a leap in quality and land in a big club.

"It is an important moment of my career and I also explained that to the leaders of Wolfsburg. With them I have a wonderful relationship and I am sure they will fulfil my desire."

Meanwhile, Wolfsburg have confirmed that striker Obafemi Martins is set to leave the club.

The Nigeria international is expected to team up with Russian champions Rubin Kazan after a less than successful first season in the Bundesliga.

He left Newcastle United last year for Germany, but after making just 16 appearances for the Volkswagen Arena-based club, he is set to move on once again.

Bayern Munich insist that they have not received any formal offers for Germany forward Thomas Muller, who is a rumoured target for several clubs in England.

The 20-year-old, who has impressed at the World Cup finals in South Africa, is under contract with Bayern until the summer of 2013 and the German champions are in no mood to part with one of their star performers.

Director of sport Christian Nerlinger told Sport Bild: "We are going to give Thomas Muller a raise.

"Bayern Munich is known as a club that will always come up with a reaction when there have been impressive performances. I am still fine with that, we have not extended the contract of Thomas Muller for no reason.

"Thus far we have not received any concrete bid for the player and we do not intend to sell him."

VfB Stuttgart director Jochen Schneider says that the Bundesliga club have yet to field an official offer for Germany midfielder Sami Khedira, who is a rumoured target for Real Madrid.

The 23-year-old has impressed for his country at the World Cup finals and is reported to be interesting Bayern Munich and Chelsea, as well as Spanish giants Real.

However, Schneider told Kicker: "We have not received any official offers for Sami Khedira so far.

"Not from Real Madrid and not from any other club. No side has even approached Stuttgart to ask about his availability."
