Borussia Dortmund chief executive Hans-Joachim Watzke has scotched rumours Bayern Munich's unhappy Germany forward Mario Goetze could return to the 2013 Champions League finalists at the end of the season.

The 23-year-old Goetze made a rare start in Germany's 4-1 thumping of Italy on Tuesday at Munich's Allianz Arena then played in Bayern's 1-0 home win over Eintracht Frankfurt on Saturday.

But the World Cup winner has now started just six of Bayern's league games this season.

He is struggling for match time under Bayern coach Pep Guardiola after a four-month absence with a groin injury.

Goetze has been linked to Liverpool, and a reunion with his ex-Dortmund coach Jurgen Klopp, or a return to Borussia's Signal Iduna Park, but Watzke ruled out the latter - for now.

"Mario is a player at Bayern. He's there until 2017 and I have heard from neither him nor his club that either want to end the cooperation," Watzke told magazine Sportbild.

"It would be completely disrespectful if we talked about a player who is under contract at Bayern.

"This isn't a topic for us at the moment."

But Watzke foresaw that Goetze would be linked to Dortmund, who he left in 2013 for 37 million euros ($41.8m), given the Germany star's lengthy spells on Bayern's bench.

"It's been clear to me for a while, that this topic would eventually come out," Watzke told daily newspaper Die Welt.

Germany's head coach Joachim Loew has advised Goetze to talk to Bayern Munich's incoming coach Carlo Ancelotti, who will replace Manchester City-bound Guardiola, about his future in Munich.

Goetze has said he just wants to play and repeatedly brushed off questions about his future.

He played a large part in Bayern's goal against Frankfurt on Saturday at the Allianz Arena with a superb run through the heart of the Eintracht defence on 20 minutes.

His shot was blocked, but Franck Ribery volleyed home the rebound.

Goetze was taken off on 85 minutes, but earned praise from Guardiola.

"I'm satisfied with his performance. It is not easy when a player doesn't play so often, but we need him for the remaining weeks of the season," said Guardiola.

But reports from Munich suggest Goetze has doubts over his future with the Bavarian giants having failed to nail down a place in the starting team after three years under Guardiola.
