Portsmouth boss Harry Redknapp is moving for Aston Villa veteran Patrik Berger - and Olympique Lyon striker Milan Baros.
"Aston Villa don't want to hear about releasing him at present," Paska told ISM Football.
Lyon striker Baros, meanwhile, has emerged as a target for Redknapp as he looks to bolster a squad weakened by the African Cup of Nations.
And Paska claims there is already an offer on the table.
He told Czech daily Sport: "I have already given the official offer of Portsmouth to Lyon's management.
"Their coach Harry Redknapp has an eminent interest in Milan."
