Well Celtic's joy at qualifying for the Champions League group stage was checked with a heavy dose of reality this evening.
The Parkhead side slumped to the heaviest European defeat in their history, undone by the genius of Barcelona's deadly attacking trio.
Lionel Messi bagged three of the seven goals to become the first player in history to score six Champions League hat-tricks. Neymar provided an extraordinary four assists and helped himself to a goal as well, while Luis Suarez notched a double to compound Celtic's humilation. In amongst all that was as sublime a volleyed goal as you are likely to see from Andres Iniesta.
Things may have been different if Moussa Dembele had converted a first-half penalty with the score at 1-0, but with Barca in this form it is hard to imagine that they would not have found a way to win even if they had been pegged back at that stage.
It was simply a mesmerising display from Luis Enrique's men, who will take some stopping as they go in search of a sixth European Cup.
Celtic will look to bounce back in Champions League Group C, but things don't get much easier as it is Pep Guardiola's Manchester City next up at Celtic Park on 28 September.
Thanks for your company and contributions this evening.
