Bayern Munich attacker Thomas Muller has confirmed that he is not going to leave the Allianz Arena but stressed that he cannot assure his current employers that he will remain forever with them after being linked with Manchester United.

In their first season without Sir Alex Ferguson, Manchester United have endured a disastrous season and are set to miss any European competition in 2014-15 for the first time in many decades. It is being consistently reported that United management is going to overhaul their ageing squad completely in the summer and Muller is their primary target, along with fellow German Toni Kroos.

Now, Muller himself has come forward to squash any rumours linking him with the English champions.

“I didn’t invent the rumours, so I can’t comment on them,” he told German newspaper Bild.

“Let’s say this: I’m certainly not about to move but I can’t guarantee that forever.”

Bayern Munich lost 5-0 to their fierce European rivals Real Madrid this week and Muller is very disappointed with the loss. He said: “Of course it hurts, but you have to be honest and say that Real Madrid were better than us over both legs. After all, we lost 5-0.

“But this criticism just goes to show our quality. Many people expected us to retain the treble.”

In this prolonged interview, Mulles also give his opinion about the upcoming World Cup in Brazil.

“We’re certainly not going to Brazil for a holiday,” he said.

“The Germany team are one of the favourites, like Brazil, Spain, Argentina and Italy. And Netherlands are like a secret favourite this year.

“I will do everything possible to win the Golden Boot again, even if it’s not realistic. You need a bit of luck for this.”

Muller Must Stay in Munich: Bayern Legend Franz Beckenbauer 

Amidst all the speculation surrounding the future of Thomas Muller, Bayern legend Franz Beckenbauer has now come forward to advise the German against a move away from Bavaria.

“You shouldn’t keep passengers, but they should fight to keep Thomas Muller if he has such plans,” Beckenbauer spoke to German newspaper Bild.

“He is an established figure under Pep Guardiola. So they (Bayern management) should do everything possible to keep Muller. They should only look for another solution if he refuses categorically.”

Manchester United are in desperate need of powerful midfield improvements and Muller fulfills the criteria. United are also said to be interested in Sporting Club de Portugal’s William Carvalho. But Sporting president Brunode Carvalho has stressed recently that his namesake will remain in Portugal next season.

Now, with negative news coming in from both Portugal and Germany, only realistic and quality option for Manchester United is Ander Herrera of Athletic Bilbao. United missed on the Spaniard last summer but are expected to make another move in coming transfer window.
