The Hoops endured a mixed season despite clinching the Scottish Premiership title.
Callum McGregor has admitted that the disappointment from Celtic's failure to reach the Champions League group stage last season still lingers as they prepare to make their bow in this year's competition, the Evening Times reports.
After a comprehensive victory over Icelandic side Stjarnan and a narrow win against Qarabag, the Hoops were knocked out at the play-off stage for the second consecutive year as Malmo claimed a 4-3 aggregate win.
Ronny Deila was unable to lead the Hoops to the group stages during either of his seasons in charge
And with their premature exit leaving a dark cloud over Parkhead that arguably contributed to Ronny Deila's exit this summer, McGregor has conceded that their failure still hurts, but insisted that the Bhoys must use that to motivate them this time around.
"The disappointment is there," he told the Evening Times.
"We will try and draw from that and we will try and do better.
"That is in the players' minds. We are all desperate to get there.
"The manager has got the experience and if we work hard together then there is no reason why we can't get there."
The optimism that has been generated following Brendan Rodgers' appointment should enhance their hopes of enjoying success this time around.
And given their struggles in previous years, there is little chance of the side going into each tie with any complacency as they know that even if they go on to win the Scottish Premiership title and do well in the domestic cup competitions, not reaching the group stages in Europe will see their season reviewed in a much more mixed light once again.
