Blackburn Rovers midfielder Vince Grella is a reported target for Houston Dynamo and Philadelphia Union.
The 32-year old injury-prone Australian has struggled for game time since his move to Blackburn from Italian club Torino in 2008 and could be keen to move on for a new experience.
2011 MLS Cup runners-up Houston and third-year club the Union are believed to be keen on Grella, who has also played for Parma and Empoli during his career, but he may play out his current contract at Ewood Park.
