Barcelona's recent woes in the Champions League were compounded in devastating fashion on Friday night.

The Blaugrana went into their quarter-final tie with Bayern Munich as the underdogs, but the majority of football fans still saw scope for Lionel Messi and co. to progress with an upset.

However, any such suggestions were blown out of the water in spectacular fashion as Barca were on the end of a thrashing of generational proportions - shipping eight goals in Lisbon.

Bayern Munich 8-2 Barcelona

Strikes from Ivan Perisic, Serge Gnabry, Joshua Kimmich and Robert Lewandowski as well as braces courtesy of Thomas Muller and Philippe Coutinho executed the historic thrashing.

In terms of consolations for Barca, they had experienced minor hope thanks to David Alaba's equalising own goal, while Luis Suarez had briefly made the scores 4-2 after the break.

However, there was no denying the better team on the night with the Bavarians not only booking themselves a place in the semi-finals, but plunging their opponents into disarray in the process.

Barcelona's European woes

As we said at the top of the article, the 8-2 humiliation has compounded Barca's recent plight on the European stage and it's starting to feel as though the Champions League is their kryptonite.

Such a devastating result has encouraged supporters to cast their minds back to matches of equal madness and Brazil 1-7 Germany seems to be the closest relative to Friday's events.

Here at GIVEMESPORT, however, we've touched on some of football's most humiliating results very recently and we want to put Barcelona in particular under the spotlight.

In fact, we've decided to shine a light on Barca's most humiliating Champions League defeats since Pep Guardiola took over in 2008 and 10 results immediately come to mind.

Barcelona's 10 humiliations

So, buckle yourselves in or - in the case of Barca fans - hide behind the sofa because here are the 10 times the Blaugrana have been humiliated in the Champions League over the last 12 years.

1. Barcelona 2-3 Shakhtar Donetsk (2008/09) 

We're starting light because, well, Barca actually won the Champions League in this particular season and Carles Puyol was hardly kicking himself about this group game when he lifted 'Big Ears' in Rome.

So, sure, perhaps 'humiliation' is a strong word, but shipping three goals at home in a defeat to Shakhtar is certainly nothing that Guardiola will have taken a shred of pride in.

2. Barcelona 1-2 Rubin Kazan (2009/10)

And there was to be more disappointment against Eastern European opposition at Camp Nou the following season in one of the biggest giant killings in Champions League history.

The reigning champions found themselves 1-0 down within two minutes and although Zlatan Ibrahimovic drew the scores level, Gokdeniz Karadeniz scored a historic winner in the 73rd minute.

3. Celtic 2-1 Barcelona (2012/13)

Look, Celtic are a legendary European side, so losing to the Glaswegians isn't too embarrassing on paper, but it's the iconic FIFA-like nature of the defeat that makes this a 'humiliation'.

Barca somehow came up short at Celtic Park despite having 89% possession, taking 23 shots and making almost 800 more passes than their opponents.

Oh, and it was 18-year-old Tony Watt, now of Motherwell, who scored the winner against Messi's star-studded side.

4. Bayern Munich 4-0 Barcelona (2012/13)

Ah yes, this week isn't the first time that Bayern have dished out big fat humiliation on their Catalan rivals, romping to a 4-0 victory thanks to Thomas Muller's brace as well as goals from Mario Gomez and Arjen Robben.

5. Barcelona 0-3 Bayern Munich (2012/13)

... and it arguably got even worse during the second leg as, frankly, Bayern looked like the home side at Camp Nou with strikes from Robben, Muller and a Gerard Pique own goal making it an astonishing 7-0 win on aggregate.

6. Paris Saint-Germain 4-0 Barcelona (2016/17)

Now, you could probably contest this game's inclusion because, as we all know, Barca followed it up with one of the greatest comebacks in sporting history by winning the second leg 6-1 in Spain.

But let's not pretend as though being hammered 4-0 at Parc des Princes, courtesy of goals from Angel Di Maria (x2), Julian Draxler and Edinson Cavani, wasn't humiliating immediately afterwards.

7. Juventus 3-0 Barcelona (2016/17)

Ok, this might not have 'humiliation' written all over it, but we think it just about qualifies by way of Barcelona being rungs upon rungs below Juventus in quality during this brutal night in Turin.

It says a lot that Paulo Dybala was the best Argentine forward on the day, helping himself to a brace, while Giorgio Chiellini killed off the tie with a third goal after half-time.

8. AS Roma 3-0 Barcelona (2017/18)

Ah, now, this is the first of the comeback humiliations with Barca entering the second leg of their quarter-final confident that they'd already progressed by having won the first match 4-1.

But the 'Greek God in Rome' that was Kostas Manolas sent Barca unexpectedly crashing out of the competition as he secured a 3-0 win for the Italians after Edin Dzeko and Daniele De Rossi's strikes.

9. Liverpool 4-0 Barcelona (2018/19)

After bottling a three-goal-first-leg lead the previous season against Roma, surely Barca wouldn't let the exact same thing happen at Anfield having won 3-0 on home soil? Yeh... about that.

The Blaugrana were once again left to lick their wounds after doubles from Divock Origi and Georginio Wijnaldum seriously cast their mental strength into doubt.

10. Barcelona 2-8 Bayern Munich (2019/20)

And here we are, the humiliation to end all humiliations and if there's any positive for Barca to take from this, any at all, it's the fact that things can't possibly get any worse.

That being said, it won't stop every Barca fan under the sun being tagged in 'you 8-2 to see it' memes for approximately the next 20 years.

GIVEMESPORT's Kobe Tong says

Ok, ok, let me sweep in for a second and add some positives, because I feel as though Barcelona fans will be lacking much in the way of optimism right now.

It goes without saying that Barca did indeed win the Champions League on three occasions during the epoch in question and it's only very recently that the upsets have become systemic.

And that's where the negatives creep back in again - I'm sorry, I'm sorry - because going three seasons on the bounce suffering some sort of humiliation simply cannot be ignored.

p1efnl18mb1a9h1dh96g6u9hkojq.jpg

To bottle comfortable aggregate leads against Roma and Liverpool is one thing, but to be on the receiving end of a thrashing of historic proportions is a completely different beast.

Forget going back to the drawing board, Barca need to go back to when the drawing board was still a tree somewhere.

It's a sad state seeing Barca this way and I take absolutely zero pleasure in it, trust me, but that's exactly why people like myself are so impassioned to see change at Camp Nou before it's too late.

Barca pride themselves on being more than a club and at the very least, they need to be more than a club that gets slapped about 8-2.
