Back in 2006, Celtic travelled to Ibrox under Gordon Strachan with a healthy lead at the top of the table. 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.

Former Manchester United captain Roy Keane started in midfield with Neil Lennon and the Irishman provided a masterclass in central midfield, breaking up play, finding passes and protecting his defence.

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.
