Liverpool boss Rafa Benitez is pushing Peter Crouch towards Aston Villa.
Martin O'Neill has been offered Scott Carson, Jon Arne Riise and Crouch for Barry but Liverpool wanted cash as well - something O'Neill is reluctant to pay as he regards Barry as more valuable than Crouch, who only has one year left on his contract.
Crouch is interested in a return to Villa Park but he also has a strong loyalty to Portsmouth boss Harry Redknapp, while a move to Manchester City would allow him to keep his north-west home.
