Sky Sports understands a number of clubs are waiting in the wings to make a move for Blackburn defender Scott Dann before the transfer window closes.
Blackburn are already struggling to keep hold of wantaway defender Chris Samba and it is believed they risk losing Dann this month as well.
The possible departure of Samba could spark a bidding war for Dann with club's hoping to capitalise on Blackburn's troubles by making a move for the highly-rated central defender.
Aston Villa boss Alex McLeish is keen on being reunited with Dann having worked with the 24-year-old during his time in charge of Birmingham.
McLeish is looking to bolster his defensive options with the likes of James Collins and Richard Dunne both linked with moves away from Villa Park.
Dann is thought to be McLeish's top target and it is thought he could be willing to offer Blackburn Collins plus cash to try and strike a deal for Dann with Welsh international Collins already on Blackburn's list of targets should they lose either Dann or Samba this month.
Arsenal and Liverpool are also thought to be monitoring developments at Ewood Park with both clubs keen on Dann before his switch to Blackburn last summer.
Both clubs expressed an interest in Dann last summer, but with the player having missed the second half of last season with a hamstring problem they had reservations over his fitness.
Dann has recovered from the hamstring problem and has made 11 starts for Blackburn this season priot to picking up a groin problem just before the busy festive period.
However, Dann has recovered from the groin injury and is set to return to the Blackburn side for the trip to Everton this weekend after returning to full training and clubs are set to watch the former England Under 21 at Goodison Park.
Reds boss Kenny Dalglish is thought to be a long-term admirer of Dann and was keen on signing him before Liverpool director of football Damien Commoli pushed for a move for Sebastian Coates.
Uruguyan international Coates has struggled to establish himself at Anfield since his arrival and with Jamie Carragher playing more of a back-up role at present, Dalglish could rekindle his interest in Dann.
Arsenal chief Arsene Wenger is tracking Dann as he considers bolstering his rearguard with the club struggling at the back this term and also seeing his defensive options decimated by injuries.
