Leigh Griffiths admits it's up to Celtic's players to get supporters back onside after their devastating Champions League exit at the hands of Cluj.
The Parkhead faithful were left stunned as Dan Petrescu's side secured a historic 4-3 win over the Hoops to reach the playoff round.
Griffiths, along with his team-mates, have been left licking their wounds and the Scotland international concedes the players are unlikely to see anything like a sell-out when they face Dunfermline in the Betfred Cup on Saturday.
Celtic are red-hot favourites to see off Stevie Crawford's Championship side and Griffiths admits he has no problems with supporters venting their frustrations in the wake their sorry Euro night.
He said: "We win as a team and lose as a team but the fans are more hurt than we are and rightly so.
"They pay good money to come and watch and expect us to get to the Champions League.
"It's very difficult to get there but the fans' expectations have grown over the last few seasons.
"I don't think they'll be happy. Am I expecting a sell-out crowd? No. But they are entitled to show their frustration.
"It's up to us to put performances on to put bums back on seats."
