Maciej Zurawski admits his time at Celtic left him depressed.
The Polish international ended a frustrating period at Parkhead with a deadline-day move to Greek minnows Larissa.
Desperate to stake his claim for Euro 2008, the 31-year-old believes the climate in Greece will enhance both his mood and his career after enduring a dire end to his two-and-a-half years in the 'dark land' of Scotland.
"It was hard to live with the knowledge that I wasn't needed any more. I could have stayed with Celtic and waited until my contract ran out in four months but I wouldn't even have had a sniff of a football pitch.
"No coach would bet on a guy who was about to leave the club. Besides, Strachan had just brought in two new strikers, so I wouldn't even have had a place on the bench."
One of Strachan's first signings in a £2million deal from Wisla Krakow, Zurawski enjoyed a highly successful first season before injury misfortune struck.
An introverted character, the striker remained an enigma to colleagues and fans until the end, yet insisted: "I don't regret a single day I spent in Glasgow - I don't divide my time with Celtic into good moments and bad moments.
"In the Champions League I didn't get the chance to do anything, it's sad but true. But I will fly to Glasgow one more time to say goodbye to everybody, even though I told them all I would be leaving in December."
