Liverpool midfielder Lucas Leiva has vowed to return stronger from a knee injury which has ended his season.

The Brazil international damaged the anterior crucial ligament in his left knee during Tuesday's 2-0 victory over Chelsea in the Carling Cup quarter-final at Stamford Bridge.

Lucas was carried from the field on a stretcher after a clash with Juan Mata and his - and the club's - worst fears were confirmed by a scan. The 24-year-old was inundated with messages of goodwill on Twitter and he responded in kind, writing: "Just to confirm that I will be out until the rest of season."
