Borussia Dortmund in talks over Mario Gotze return

Gotze moved from Dortmund to Munich for 35million euros in 2013 but has not featured as much as he might have expected and a return is now being discussed.

"I wouldn't say a deal has been struck, but I can confirm that there have been talks with Borussia Dortmund as well as with his agent," Rummenigge told Sport1 television ahead of Bayern's friendly against Lippstadt on Saturday.

"But it's not complete yet. The clubs must first reach an agreement over a transfer fee."

Dortmund are likely to receive a substantial discount on Germany's World Cup-winning goalscorer, with Rummenigge accepting Gotze did not meet expectations.

"He's been here for three years and it's not worked out," Rummenigge said. "It's not surprising that he has had a change of heart.

"He's 24 years old and he needs to be playing regularly."

Gotze scored 31 goals in 114 appearances in four seasons at Dortmund. While his scoring rate has improved in a dominant Bayern team, with 35 in 85 games, he has completed the full 90 minutes on only 27 occasions in three seasons.
