Bayern Munich legend Steffen believes a transfer “shouldn’t be an issue” for the Manchester United target Toni Kroos and insists he should think carefully before seeking an exit from the club.

The German international has long been linked with a move Manchester United who are believed to be  offering Toni Kroos £260,000 a week as they continue to try to prise the midfielder away from Bayern Munich this summer.

The 24-year-old’s current deal with the Bundesliga champions expires in June 2015 and Effenberg has warned the playmaker to think carefully over whether he really wants to leave the German giants.

Steffen Efenberg spoke to Football website He said: “Put it this way: If you have the opportunity to form a successful era at Bayern, you should think two or three times about what step to make.

“Every player feels enormously well in Munich and at the end of the season, there are titles. Kroos is a key figure, a transfer shouldn’t be an issue.

“He is an important and crucial player – for the system and the new philosophy.”

Mario Mandzukic’s future has been a subject of debate recently although, with Arsenal having been linked, Effenberg remains confident that the striker will be stay and fight for his place despite the impending arrival of Robert Lewandowski.

“We don’t know where [Mandzukic] is heading,” the former Germany international added. “He said publicly that he has no worries, is not afraid of competition.

“He will accept the challenge. They always say ‘Bayern have a huge squad but are only allowed to play with eleven players’. Then injuries come and the whole discussion is finished. A lot of things adjust themselves.”

United have struggled under Moyes this season and will not play in next season’s Champions League. However, the club hope that the sizeable financial offer to Kroos plus United’s rich pedigree could yet persuade him to leave the Bundesliga champions who have a chance of being the first club to retain the European Cup in the Champions League era.

Kroos impressed during each leg of Bayern’s 4-2 aggregate win over United in the recent Champions League quarter-final. Playing as a deep-lying midfielder, he was the chief orchestrator of attack for Pep Guardiola’s team. It is this role that Moyes wants to fill at United and Kroos would be a player around whom the next United manager could build his team for the foreseeable future.

And whoever comes into the job will, of course, have a huge influence over who is brought to the club and will be key as to whether the Red Devils can sign long-term target Toni Kroos.

While Moyes was in charge, it did seem unlikely that Kroos would be tempted away from the European champions, especially as United’s 2-0 loss to Everton confirmed they will not be in the Champions League next season. However, if Van Gaal is brought in to replace Moyes in the long term, the 24-year-old may think again about whether to commit his future to Bayern.
