Borussia Dortmund have warned Arsenal that midfield ace Mario Gotze is not for sale.

The Gunners are still ready to make a bid in January.

However, Dortmund director of sport Michael Zorc said: "All the relevant people have all said clearly that there will be no transfer for Mario Gotze.

"In football, things are never 100 per cent but I'll say I am 99 per cent, maybe more, sure that Mario Gotze will play next season at Borussia Dortmund.

"Now you can throw the topic in a heavy chest and let cobwebs grow on it."
