Bayern Munich vs Barcelona has started in truly remarkable fashion in Portugal tonight.
The clubs entered the game as the two sides with the most Champions League pedigree with captains Lionel Messi and Manuel Neuer having both won the competition in their careers.
As a result, perhaps the biggest shame about the all-star clash in Lisbon was that it came so early in the competition.
Crazy start in Lisbon
But quarter-finals or not, the game didn't fall short of its expectations and Bayern, the favourites on the night, took the lead after just four minutes with a goal that Barca would have been proud of.
And it was Thomas Muller, a veteran of the infamous 7-0 aggregate win from 2013, that provided the finishing touch by finding the bottom corner after a one-two with Robert Lewandowski.
In fact, Muller has something of a penchant when it comes to scoring against Barcelona on the European stage with his opener making it five goals in as many games.
David Alaba's awful own goal
However, any advantage that the Bavarians looked to have claimed from their own tiki-taka impression was chalked out in the most astonishing fashion just a few minutes later.
David Alaba has unexpectedly made a name for himself in the centre-back position this season, playing inside Alphonso Davies, but he did himself no favours during the Barca clash.
That's because he scored one of the worst own goals you'll see all season by shanking Jordi Alba's cross over Neuer and into the far top corner. It was, by all accounts, a remarkable finish.

Things became even crazier in the aftermath of the back-to-back goals, too, with Luis Suarez having the opportunity to turns things around by going one-on-one with Neuer.
And although the Bayern 'keeper won that particular battle, the Blaugrana did indeed beat the German international just moments later, but it was the post that denied Messi's own opening.
Two goals within the opening seven minutes and chances galore. Get yourself some popcorn, we've got ourselves an absolute cracker.
