Lucas was voted Player of the Year last season at Anfield, but Liverpool boss Kenny Dalglish has spent £49million on midfielder this summer.
Stewart Downing, Jordan Henderson and Charlie Adam are the trio who have joined the Reds.
Lucas has stated that he is not prepared to sit on the bench at Anfield and could leave the club in the summer.
A source told The Sun: “Lucas only signed a new deal in March and was voted Player of the Year by the fans.
“But the word is he is leaving and that will shock a lot of people, especially after he played so well last season.”
