Celtic captain Callum McGregor insists he can't wait to lead the club back into the Champions League.

McGregor skippered his side to back-to-back titles - his fourth as captain and 19th trophy success in all - which once again gives automatic entry into the lucrative Champions League group stages.

Ange Postecoglou's managed just two points from a possible 18 in six group stages matches last season after pitting their wits against Real Madrid, RB Leipzig and Shakhtar Donetsk.

McGregor lifted the trophy as Celtic signed off in style with a 5-0 win over Barry Robson's Aberdeen at Parkhead with a double from Kyogo Furuhashi and a brace from Oh Hyeon-gyu and a counter from Carl Starfelt.

It was the perfect tonic ahead of next weekend's Scottish Cup final against Inverness Caledonian Thistle at Hampden Park as Celtic stand 90 minutes away from creating a slice of history by securing an unprecedented eighth domestic treble which would be a new world record.

McGregor admits that it will feel great to sample the delights of top tier European football once again.

He also revealed that it was a joy to play in this Celtic team under Postecoglou with the backing of an amazing fanbase.

McGregor said: "Firstly I'd like to say to play in a team that is so aggressive in the way that we try and play football and it's an absolute pleasure to play with these guys every day and to be led by the manager and led by this unbelievable support.

"To lead this club back into the Champions League is what everyone wants. It is so important to this club to be back in the elite level of the Champions League.

"It is so, so important for the supporters and the club and we can't wait to have another crack at it."

And Postecoglou was keen to praise everyone involved in the club at full-time.

He said: "Champions again," he said. "We are champions again because of this incredible group of players who are brilliantly led by our skipper Callum McGregor.

"Champions again because of this unbelievable group of people working behind the scenes as staff.

"Champions again because of you. In the words of the immortal Tommy Burns, 'you are always there, always.'

"Champions again because I am a lucky man.

"And we have more to go because we never stop."
