Manchester United and Arsenal target Mario Gotze will stay with Borussia Dortmund for at least one more season, according to sporting director Michael Zorc.
Gotze is regarded as one of the finest young prospects ever produced in German football and, thus, has frequently been linked with a move away from Dortmund.
Old Trafford and the Emirates Stadium have been touted as potential destinations for the 19-year-old, as Sir Alex Ferguson and Arsene Wenger look to reinforce their midfield ranks.
But, joked Zorc, Gotze will not be joining United and Arsenal - or anyone else for that matter - unless an offer in the region of €1 billion is made.
"We have agreed with Mario that he plays next season in Dortmund," Zorc told BILD.
"He has the contract to 2014 - we have no reason to sell him. But I am not a prophet. If tomorrow someone offers one billion euros, then you should think about it."
