Celtic manager Gordon Strachan has quit following their failure to clinch a fourth successive title.

The club announced on their website that Strachan - who won three titles and three domestic cups in his four years in charge - had decided to step down.

Strachan said: "I have enjoyed my time immensely at Celtic and clearly I will be sad to leave this great club."

Strachan refused to discuss his future immediately after their final Clydesdale Bank Premier League game of the season, a 0-0 draw with Hearts.

But his departure is no surprise after he failed to gain total support from a number of Celtic fans despite his success at home and in Europe, where he twice led Celtic into the last 16 of the Champions League.

Strachan added on celticfc.net: "As I have said before, Celtic is a special club, with special supporters.

"There is no club like it and it has been an absolute honour and privilege to be the club's manager for the past four years.

"We have done all we can to bring success to the club and we were delighted to deliver three SPL titles, other domestic silverware, as well as making some great progress in Europe.

"It is just disappointing that we did not manage the fourth championship.

"However, the players can hold their heads high in terms of what they have done for the club in recent years."
