Arsenal have been told by Borussia Dortmund that they must increase their bid for forward Mario Gotze.
It had been reported that the Gunners were ready to offer £25m for the 19-year-old.
Dortmund have now said that they will not accept anything less than £30m, according to talkSPORT.
The revised figure means that Arsenal would have to break their own transfer record for the player.
