Celtic took their recent UEFA Champions League frustrations out on Hibernian in the Scottish Premiership on Saturday as they ran out 6-1 winners.
The Hoops suffered consecutive Champions League defeats on Wednesday after losing 2-0 to RB Leipzig at home.
That defeat has all but ended Celtic's hopes of progressing to the knockout stages with two group games remaining.
Ange Postecoglou has faced some criticism for not adopting a more defensive approach in Europe with the Hoops conceding nine goals across four games.

But it has been a misfiring frontline that's really cost Celtic, with the side scoring just twice in the Champions League this campaign with Postecoglou relieved to seem them find their spark again against Hibernian.
The Hoops coach believes the 6-1 win highlighted why his team didn't deserve some of the comments directed their way after the loss to Leipzig.
"We needed fresh impetus and the whole group was great. For the guys who came in, that was exactly what they provided for us," Postecoglou said after the Hibernian win via the BBC.
"I was really strong on the fact that, if we put on a performance like we did on Wednesday, the goals would come. It's why I thought some of the Champions League comments were ridiculous.
"We set out to play a certain way and we've fallen short in areas where, for the most part, I think we can improve, but it's not through a failure of endeavour or will.
"We will never change our approach and the players wanted to show that today."

James Forrest scored a hat-trick for Celtic against Hibernian with Postecoglou rewarded for giving the club veteran a rare start this season.
"It's exactly why we wanted to keep him at the club. A successful squad is made of many parts. I knew James would be an important player for us over the year," Postecoglou said.
"He's been chipping away at it and has made an impact every time he's come on over the past few weeks. He was ready today and I know there's more to come."
Socceroo Aaron Mooy also put in one of his best Celtic performances to date, with the Australian midfielder claiming two assists as he played the full 90 minutes.
Postecoglou's side next face Motherwell in the league on Wednesday night (local time) and are currently five points clear at the top of the table.
