On This Day in 2006, Roy Keane showed his class after putting on a show of sheer grit and determination as Gordon Strachan’s Celtic beat Rangers 1-0 at Ibrox. After signing for Celtic at the end of December from Man Utd, Keane arrived with enormous fanfare having been one of Sir Alex’s most trusted advisors.

The former United captain started in midfield with Neil Lennon and the Irishman provided a masterclass in central midfield, breaking up play, finding passes and protecting his defence. A colossal 18 points separated the teams and that stood at 21 points when Zurawski slotted the ball into the net after just 12 minutes.

Keane made just 13 appearances for Celtic, scoring once before he was forced to retire. It is a shame that fans were only limited to such a small amount of games watching Keane as games like this showcase how good a player he still was, even if he was in the twilight of his career.

Keane would help Celtic complete a double that season with the League Cup and League, his last as a player. Keane has made the move into management and coaching since retiring but he continues to earn the headlines for his work as a pundit.
