Arsenal are interested in Borussia Dortmund defender Neven Subotic.
The American-raised Serbia international has been a long-term target for several Premier League heavyweights, including Arsenal.
Gunners boss Arsene Wenger is seeking a new centre-half signing and may be forced to turn to Subotic should he lose out to Chelsea for Bolton Wanderers' Gary Cahill.
Wenger's interest opens the door to a swap involving Nicklas Bendtner. The Dane is wanted by BVB, though they refuse to consider meeting his £10 million asking price.
