The strikers have spent the last six days working in Scotland with the SPL champions after arriving in Glasgow last Friday.
And they took part in a bounce game amongst squad members at Murray Park as the manager and his assistant Kenny McDowall took the opportunity to see them in action.
Chhetri and Lalpekhlua will now resume their careers with their clubs in the I-League but McCoist is ready to keep a close eye on how they progress.
He had this to say: “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 today but we will keep monitoring their situations and keep monitoring 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.
“It was a good experience for them and I think they certainly enjoyed it. We enjoyed having them here too.
“Kenny and I watched them playing in the match yesterday and it was a really enjoyable game. They did absolutely fine.”
