Along with his India team strike partner Jeje Lalpekhlua, Chhetri had flown to Glasgow to attend a trial, but felt he never got enough opportunities to impress manager Ally McCoist.
"On the first day we came here they were preparing for a match the day after, so we couldn't train. The second day was the match, then the third day they had to rest after the match. On the fourth day they left for Hamburg and we couldn't go. It was a bit disappointing," Chettri said.
"But this was the only week we had a break in our league. It was the only chance I had to come and have a trial. I'm just disappointed I didn't get much time with the first team. Even the gaffer didn't get much time to see us," Chhetri was quoted as saying by Scottish newspaper 'Daily Record'.
Chhetri though added that he would love to try his luck one more time.
"If given a chance, Jeje and I would love to come back, in the summer hopefully. It is a huge club with a huge history and we'd love be a part of it."
McCoist had earlier said that the club would keep a tab on the performances on the two Indian players.
"Sunil and Jeje did fine and showed up well in training. They showed some lovely touches and adapted to the different surroundings they experienced.
"They are away back home - but we will keep monitoring their situations and their performances back home. They will continue to play for their sides in India and it was great to have them both working with us as they are talented boys," McCoist added.
