Bayern Munich chief executive Karl-Heinz Rummenigge has confirmed the Bundesliga giants are interested in securing the services of the coveted Borussia Dortmund forward Marco Reus.

The 25-year-old star's future at the Jurgen Klopp's side has been under increasing scrutiny since it was revealed he has a special release clause in his contract that allows him to leave the team next summer for as little as €25m (£20).

Dortmund have reportedly tried to convince him to sign a new deal to increase his clause, but it is understood that the player has rejected his club's approaches as he is likely to move away at the end of the current campaign.

Reports in Spain this summer claimed Real Madrid had a first option on Reus' future while Manchester United, Liverpool, and Arsenal are also reportedly monitoring the situation.

While the player keeps refusing to confirm whether he will leave or stay at Dortmund next summer, Rummenigge has once against suggested Bayern will plan to launch a bid for his signature.

"We know what quality he has and we also know what clause he has," Rummenigge said to Sport1.

"A young, Germany international with such quality is probably interesting for us, but I don't want to cause any ill-feeling with Dortmund."

However it is understood that Real Madrid and the Premier League giants will have an advantage to secure his services over the Bundesliga champions due to the tense relationships between Dortmund and Bayern.

Nevertheless, Klopps' side have seen both Mario Gotze and Robert Lewandowski leaving their ranks for their big rivals in the last two summers and will try to avoid this situation with Reus.

"Borussia Dortmund have informed us that they don't see any point in eating together with Bayern Munich," Rummenigge admitted.

"Of course our relationship with Dortmund is not good."
