After being confirmed to be out of action until the end of the season, Lucas Leiva has undergone an ankle surgery to repair the anterior cruciate ligament damage he sustained during the match against Chelsea.

Lucas played in the 2-0 win over Chelsea, but he sustained a horrible injury in the process. Despite making into the Carling cup semi finals following the win, one can certainly be confident that Kenny Dalglish would have not played him in hindsight. He has been praising Lucas Leiva lot in recent weeks by saying that the recent form of Liverpool has to be attributed to the Brazilian.

He seems to have come of age of late after performing poorly under the reign of Rafa Benitez. Further, the departure of Mascherano to Barcelona also seems to have helped his cause. The regular run of games that he now gets in the midfield has been one of the main reasons for Liverpool to not feel the absence of Steven Gerrard in recent weeks. However, the injury that he sustained in the match against Chelsea is a crucial one and it will rule him out for the season. Liverpool confirmed that the Brazilian had indeed undergone a surgery and will be starting his recuperation period immediately.

"Liverpool confirmed this afternoon that Lucas had successfully undergone surgery in Brazil on the Anterior Cruciate Ligament injury he sustained at Chelsea last week. LFC medical staff were present during the procedure. Lucas will now begin an agreed rehabilitation programme which will be overseen by the Club's medical team," read a statement on Liverpool's official website. A number of his teammates have been tweeting about the fact that they will be missing him for the next few months, which will be crucial because Liverpool need to qualify for the Champions League.
