Aston Villa are ready to test Blackburn's resolve as they hope to make a move for international midfielder David Bentley this summer. O'Neill has reportedly made Bentley his priority.
With Gareth Barry set to quit the Villains, the club has plenty of disposable cash to spare.
It is understood that David Bentley could be brought in as the replacement for Gareth Barry.
Aston Villa may have to spend as much as £13 million to land the England winger.
