Callum McGregor has confessed that Celtic's recent Scottish Cup treble triumph was the "most emotional" moment of his career so far.

The captain, who led his side to consecutive league titles under former manager Ange Postecoglou, sat down with Celtic TV to discuss last season's achievements at the football club.

McGregor, 29, has revealed that Jota's goal to secure Celtic's two-goal lead at Hampden against Inverness Caledonian Thistle sent him over the edge. When asked if he felt anything at the time, he said: "Yeah, it was probably one of the most emotional I've been on a football pitch."

"When we scored the third goal with about three or four minutes to go, I'm like 'thank god we've done it' and you just get that rush of relief come through you.

"It was a long period of six months after the World Cup so there was a lot of bodies struggling as well - physically, mentally trying to get over the line.

"But when Jota scored that third one, there was a lot of relief at that moment."

McGregor succeeded longtime Scott Brown as captain following the legendary midfielder's departure to Aberdeen, winning five trophies as skipper in his own right. 

Brown was no stranger to a Champions League night at Celtic Park, something which McGregor is looking forward to next season, thanks to automatic qualification due to winning the Premiership.

McGregor said regarding Celtic's upcoming Champions League campaign: "Yeah, that's something that the club hugely relies on in terms of stature and status within European football.

"This will be the second year in a row so we have to try and normalise that. That has to become normal for the group, the club. So again, another exciting time, you go straight in which alleviates some of the qualifiers.

"So to go straight in and have that period of five or six weeks' pre-season where you can really work and detail the group and get fit, then you have that (the Champions League) to look forward to.

"And it's always a brilliant experience. Anybody in world football talks about how special the European nights are at Celtic Park and I'm sure this season will be exactly the same."
