Liverpool have confirmed Lucas Leiva will miss the rest of the season after the midfielder damaged his anterior cruciate ligament in his left knee.
The Brazilian will now have surgery to repair the damage sustained in an attempted challenge on Chelsea's Juan Mata during the Reds 2-0 League Cup victory over the west Londoners at Stamford Bridge on Tuesday.
The 24-year-old, who has had an impressive campaign for Kenny Dalglish's side, becoming an integral part of his starting XI, revealed his disappointment at the news via twitter, but insisted he will return 'stronger' and ready to succeed at Anfield.
Lucas said: "Hi all. Just to confirm that I will be out until the rest of season. I am really sad with the news because I was enjoying a lot on the pitch.
"I am sure I'll NEVER WALK ALONE.
"I am sure I will come back stronger and I will achieve everything that I dream with the LFC shirt."
Liverpool are already without captain Steven Gerrard but have recalled Jonjo Shelvey from his loan spell at Championship side Blackpool to cover for the loss of Lucas.
