Manchester United and Arsenal are being linked with Borussia Dortmund defender Neven Subotic.
The Serbia international, who was raised in the USA, has been a long-term target for both Premiership giants.
Italian sources say Dortmund are willing to listen to offers for Subotic starting at £25 million.
United boss Sir Alex Ferguson is keen, but will have to fend off interest from Arsenal for the centre-back.
