Kilmarnock target Irvine was assured on the big stage as the Hoops shocked the English giants 1-0 at Aviva Stadium.
The 20-year-old shone in a midfield battle that pitted him against the likes of Anfield legend Steven Gerrard, Joe Allen and Brazillian star Lucas.
His performance was so impressive, Gerrard gave him his shirt after the game.
Now Scottish Premier League club Kilmarnock is keen to get the Melbourne player to Rugby Park and a six-month deal is on the cards.
“Jackson Irvine is definitely one we are interested in but nothing has been sorted out yet,” said Killie boss Allan Johnston.
Irvine admits he may have to leave Celtic for the time- being if he is to become a Hoops hero in the future.
“It’s a tough decision whether to go on loan or not,” he told the Scottish Sun after the match. “My priority is to be a Celtic player, this is where I want to be.
But he added: “It’s going to be very hard to break in there. Going on loan for six months wouldn’t do me any harm — it would give me a chance to step up and play regularly.
“Hopefully I’d bring that experience back and play for Celtic. I want it sorted out in the next week. It’s all down to the manager and the talks between both clubs — I’m happy to do whatever they think will be best for my career.”
“Aside from the Hibs game, this was the biggest game of my career.
“They don’t come much bigger than this — 50,000 fans and you find yourself standing in that line when they sing You’ll Never Walk Alone.
“You probably won’t get many moments like that in your career. It was on TV in Australia so even though it was 2am in Melbourne, hopefully they saw it.”
Meanwhile Irvine attributed his composure during the win over Liverpool to manager Neill Lennon.
“The manager had a word with me to try and ensure I wouldn’t be overawed by the whole experience,” he said.
“But I didn’t have time to be fazed — I had to be on my toes for the full 90 minutes.
“I just had to treat them like another team and I felt I dealt with it pretty well. I even managed to brush Gerrard aside at one point and I got a thrill out of that.
“To do something like that was a bit surreal. He’s had an unbelievable career but maybe his legs are going a bit! Seriously, it’s scary to play against guys like him.
“I didn’t really get a chance to speak to him during the game. All the boys were saying they chatted with Liverpool players and were asking for shirts.
“But I was so in the zone I had no idea what was going on. “
Irvine played for Scotland in the U19s but switched allegiances in 2012, lining up for the Young Socceroos. The versatile player admits one of the biggest challenges is knowing where to play him.
“I played all my youth football in central midfield but we were short at centre-back last year and I filled in there,” he said.
“I’ve played in a few friendly games at the back and the coaches are still talking about what my best position is.
“But I’m more comfortable as a midfielder. I feel I can do a job anywhere for Celtic.”
