After winning the FIFA Club World Cup, on 27 December 2007, Gattuso trained with his former club Rangers to regain fitness during the Serie A winter break whilst his wife was visiting family in Scotland over Christmas. The following December, Gattuso suffered a torn Anterior cruciate ligament early on in the 1–0 league win against Catania. Despite the injury, however, Gattuso played the entire 90 minutes before being diagnosed by the club doctors after the match. He underwent surgery to repair the damage on 19 December 2008 in Antwerp, Belgium. He was expected to miss up to six months of action but managed to return to the Milan bench on 10 May against Juventus, a month ahead of schedule.
