The game of the opening Round of 32 fixtures undoubtedly goes to Celtic and Inter who shared six goals tonight.
It seemed like embarrassment was destined for the Hoops after they conceded twice in the opening 15 minutes to goals from Xherdan Shaquiri and Rodrigo Palacio.
But Ronny Deila's side fought back almost instantly and were back in it with two quick-fire goals, the first coming after Stuart Armstrong fired home a tidy finish before the Scottish midfielder's hard-work paid off and forced the ball into the net to make it 2-2 after 26 minutes.
Celtic were dealt a sucker-punch before half-time, though as Palacio scored his second to put Roberto Mancini's men ahead at the break.
It looked like defeat was on the cards for Celtic before John Guidetti latched onto a ball over the top in the 90th minute and let fly with the goal of the game to make it 3-3 in an unforgettable night at Celtic Park.
