Former Celtic winger Didier Agathe fired a scathing attack on former Celtic and Scotland manager Gordon Strachan, claiming that he was ‘everything that football should not produce’. Agathe was an integral part of Martin O’Neill’s treble-winning side of 2001 and went on to play 181 games for the Parkhead side, scoring 11 times.

When the Irishman left in May 2005, Gordon Strachan was appointed as his successor and that was the beginning of the end for Agathe at Celtic and his playing career as a whole.

He went on to play just four times under Strachan before being released from his contract in February 2006, going on to play just five more times - for Aston Villa - before returning to Réunion Island and retiring from football.

Speaking to French magazine SoFoot.com, Agathe said: “I learned a great deal from Martin O’Neill from the personal point of view. He was a proper manager, he spoke with his players and fostered a real team spirit.

“However Gordon Strachan was totally the opposite. He brought in a right-back, Paul Telfer – and the guy was married to his daughter! There you go.

“I clashed with Strachan in my very first training session with him, as I was injured and he told me to train against the advice of the physios.

“He was hung up in comparison to O’Neill. I honestly didn’t learn a thing from him, and I’m not just saying this as I didn’t get to play.

“Gordon is truly everything that football should not produce. You get the impression that he is there because of his ego, and not because he wanted to pass on any knowledge.”

Strachan would go on to manage Celtic until May 2009, leading the club to three league titles, a Scottish Cup, and two League Cups. He also guided the Glasgow giants to the last 16 of the Champions League twice.

Agathe also claimed in the interview that his car was vandalised by angry Rangers fans after Celtic won the treble in 2001 and that he had to move nine times in one season due to death threats from rival supporters.
