Celtic were put out of their Europa League misery on Thursday night as Dutch giants Ajax beat them 2-1 at Celtic Park, dumping the Bhoys out of the competition.
It all started so well for Celtic, as Callum McGregor gave Ronny Deila's men an early lead. However, Arkadiusz Milik hit back with the equaliser, before Vaclav Cerny finished off a counter-attack, as Ajax won the game late on from a Celtic corner.
It now means that Celtic have drawn twice and lost three times in the Europa League this season, and defeat to Ajax has now eliminated them from the competition.
Elimination from the Europa League is the latest blow for manager Deila, and whilst he was handed a tough group against the likes of Ajax, Fenerbahce and Molde, no excuses will wash with the Celtic fans.
Supporters had doubts over Deila after losing a two-legged Champions League play-off to Malmo in August, but were willing to see how he fared in the Europa League.
That has now gone disastrously, meaning Celtic are out of all European competition before the start of 2016 - and the frustration towards Deila is growing.
After the game, the Norwegian spoke to the club's official Twitter account, stating that Celtic will be ready for European football next season, as it's his biggest job right now.

Whether Deila's message eases the pressure on him remains to be seen, with success in the Scottish Premiership no longer enough for a Celtic manager.
Some fans are already calling for former Bhoys defender David Moyes to be appointed as Deila's replacement, and whilst it looks unlikely that Celtic make a change in the dugout right now, the doubts over Deila's ability in Europe continue to grow.
