Chelsea are in contact with minders for Arsenal striker Folarin Balogun.
The USA international has been transfer-listed by the Gunners at a starting price of 50m.
AS Monaco and Inter Milan have both made attempts for Balogun, though their offers have fallen short of Arsenal's valuation.
The London Evening Standard says Chelsea are now in contact with the player's camp.
Arsenal are aware of Chelsea's move and won't rule out selling Balogun to their London rivals.
