“AC Milan announces that today, Simon Kjaer underwent arthroscopy of the left knee for the reconstruction of the anterior cruciate ligament and the re-insertion of the medial collateral ligament”. This is the statement that recently appeared on the Rossoneri club’s website, which communicates the outcome of the Danish defender’s knee operation, after the problem reported in the first minutes of the match against Genoa. «Kjaer is well and is motivated to start the rehabilitation process immediately. The recovery times can be estimated in 6 months », reads the note again. The season is therefore over for the Milan defender, a bad blow for Stefano Pioli and the whole team, who loses a leader on a technical and character level.
