Pavel Paska told Sport: “Liverpool have a problem as Jamie Carragher has picked up a serious injury.
“Manager Rafael Benitez, together with the club director Rick Parry therefore asked me to put an offer to Tomas.
“Tomas discussed it with his family and told me that he was happy with life in Italy and that the only country he would move to would be Spain.
“I have to respect his decision, but it surprised me a lot nevertheless. Liverpool would never make this kind of offer to a player twice.”
