Celtic produced a superb comeback on Thursday night, rallying back from 2-0 down to earn a 3-3 draw against Inter Milan, with John Guidetti bagging a last minute equaliser in their Europa League tie.
The Bhoys now travel to Italy next week for the return leg, and whilst Inter will be favourites after their three away goals, Celtic still stand a chance of making it into the last 16.
Inter may have declined since winning the Champions League back in 2010, but the performances of Xherdan Shaqiri and Rodrigo Palacio proved that Roberto Mancini's men still have plenty of quality players at their disposal.
However, one of the big factors in Celtic's recovery from two goals had a lot to do with the part played by the outstanding Bhoys crowd.
There have been plenty of famous European nights at Celtic Park in recent years, including wins over Barcelona and Manchester United.
The fightback against Inter will live long in the memory for Celtic fans, and their manager Ronny Deila spoke to the press today - as reported by the official Celtic Twitter account to praise their fans, even labeling then as the best in the world.

Celtic won't have their home crowd to rely on at the San Siro next week, but there is a belief that they can still get a result in Italy after defying the odds on Thursday night.
