Pep Guardiola’s new side will trigger the bumper release clause in the contract of the Germany star.

It is a transfer that could see the talented 20-year-old play the false-nine role — like Lionel Messi — in Guardiola’s side next season.

The former Barcelona coach, who won 14 trophies in three seasons at the Nou Camp, has agreed to take over as manager this summer.

And Dortmund confirmed the first big move of the new era this morning with Gotze revealing he wants to move to the Bundesliga champions.

Dortmund CEO Hans-Joachim Watzke: “We are obviously disappointed beyond measure.

“But we emphasise both Mario and his advisers have behaved absolutely in conformity with the contract.”

Dortmund coach Jurgen Klopp and director of sport Michael Zorc have asked Borussia fans to support Goetze in his last four league games for the club.

He joined them as an eight-year-old in 2001 and is one of the rising stars of the Germany team.

Gotze made his international debut as an 18-year-old in October 2010 and scored his first goal against Brazil in August 2011.

His addition to the star-studded Bayern squad is sure to boost the Bavarian giants,

Dortmund fans have already vented their anger and frustration on Gotze’s Facebook page with “traitor” being one of the kinder comments.

Having won the German league title for the last two seasons, Dortmund have missed out to Bayern this season.

Bayern won the Bundesliga a fortnight ago with six games to spare and a 20-point lead.

Born in Allgaeu, Bavaria, only 75 miles from Munich, Gotze made his Bundesliga debut in 2009, aged 17.

He has since made 22 appearances for Joachim Loew’s Germany, scoring five goals, and is set to be one of the stars of next year’s World Cup in Brazil.
