Juventus suffered a humiliating 4-0 loss to Chelsea in the Champions League last night at Stamford Bridge.
Goals from Trevoh Chalobah, Reece James, Callum Hudson-Odoi and Timo Werner ended the Serie A outfit's winning run in the competition. The Bianconeri had entered the match on the back of a 100% record in Group H, having won all four of their matches so far.
However, a calamitous display broke the streak, with Massimiliano Allegri's team well below their best on the night.
It was their heaviest loss in all competitions since losing 4-0 to AS Roma in February 2004. But where does it rank on their list of worst Champions League defeats?
Here are their six most embarrassing results in the competition:
#6 Juventus 0-3 Manchester United (Group stages, 2003)
Juventus reached the finals of the 2002-03 season before losing to domestic rivals AC Milan in the showpiece clash. But their journey until then was rocky.
In the second group stage, the Bianconeri lost 3-0 to Manchester United at home, with the visitors cruising into the quarter-finals in style.
A double from Ryan Giggs gave the Red Devils a comfortable 2-0 lead before the break. Ruud van Nistelrooy added a third around the hour mark to complete the scoring.
#5 Barcelona 3-0 Juventus (Group stages, 2017)
Barcelona and Juventus clashed a total of four times in the 2017 calendar year. This included twice in the quarter-finals of the 2016-17 season and then in the group stages of the 2017-18 season.
The Bianconeri won the knockout tie 3-0 on aggregate, with all three goals coming in Turin. But about half a year later, the Blaugrana exacted revenge with an identical win at Camp Nou.
Inspired by the irrepressible Lionel Messi, the visitors were put to the sword that night. The Argentine netted twice on either side of a goal from Ivan Rakitic for Juve's worst group defeat since 2009.
#4 Juventus 0-3 Real Madrid (Last 8, 2018)
Another seven months later, that same season, Juventus were cooked at home by a clinical Real Madrid side in the quarter-finals. They lost 3-0 in the first-leg, with Cristiano Ronaldo now the tormentor.
The talismanic No.7 netted twice on that historic night. This included the famous overhead kick that sent the internet into meltdown and evoked a standing ovation from the home crowd.
Few had predicted that Ronaldo would end up in Turin a few months later himself. The Portuguese himself later revealed the "unbelievable" applause from Juventus fans motivated him to join the club.
#3 Juventus 1-4 Bayern Munich (Group stages, 2009)
In the group stages of the 2009-10 season, the Bianconeri only needed a draw with Bayern Munich on the final day. This was to secure a place in the last-16, and they were at home too.
But the Bundesliga giants sprung a surprise, wiping the floor with their listless hosts to secure a thumping 4-1 victory in Turin. They won comfortably despite falling behind early on after David Trezeguet's opener.
Hans-Jorg Butt equalized from the spot before half-time. Ivica Olic, Mario Gomez and Anatoliy Tymoshchuk scored in the second half to condemn Juventus into the Europa League.
#2 Juventus 1-4 Real Madrid (Finals, 2017)
Massimiliano Allegri guided Juventus to two European finals during his glorious first stint at the club, but ended up losing both. The first to Barcelona in 2015 and then to Real Madrid in 2017.
The second defeat was heavier, with Zinedine Zidane's swashbuckling team putting four past Juventus. This included two from Ronaldo which meant Real Madrid retained their Champions League crown.
It was the Bianconeri's fifth consecutive defeat in the finals, and seventh overall.
#1 Chelsea 4-0 Juventus (Group stages, 2021)
Chelsea delivered Juventus their heaviest loss of the Champions League-era last night. This was also their worst defeat in all competitions since February 2004.
Back then, AS Roma thrashed the side 4-0 in Serie A, but the Turin giants hadn't lost by a four-goal margin in this competition before.
In fact, their last 4-0 defeat in Europe came against Celta Vigo in the UEFA Cup in 2000. French legend Claude Makelele triggered the onslaught after only 27 seconds!
