ROTTACH-ERGERN  Arjen Robben hopes defender Jerome Boateng remains with Bayern Munich despite the German World Cup winner from 2014 being linked with a transfer from the club.

"Jerome Boateng is one of the best defenders in the world for me," Robben said at the conclusion of Bayern's training camp at Rottach-Egern on Thursday.

"We have already celebrated a lot of success with him, Jerome is simply very important for this team."

Boateng, 29, reportedly turned down a potential move to Manchester United in the Premier League but remains a strong contender for French champions Paris Saint-Germain, according to Le Parisien paper.

Bayern recently sold Arturo Vidal to Barcelona and chairman Karl-Heinz Rummenigge appeared open to further departures - a mistake, according to Robben.

"It is quite important that expect Arturo we have not given up anyone else," Robben said. "We have a lot of quality in the team. We have to stay together and then we can be successful."

Record champions Bayern are chasing yet another Bundesliga title and Robben did not predict who would offer the biggest challenge to their dominance.

"We will see," the 34-year-old said. "But we have to make sure that we are not our own opponent. We have to look at ourselves."

Bayern face Eintracht Frankfurt away in the Super Cup on Sunday before the German Cup begins next weekend and they start the Bundesliga at home to Hoffenheim on August 24.
