Bayern Munich came from two goals down to beat Juventus 4-2 at the Allianz Arena and progress to the Champions League last eight.
But what did we learn? How was Kingsley Coman allowed to play against his parent club? Could this win give Pep a much-needed boost for the final quarter of the season? And does Juan Cuadrado have a future at Chelsea?
Here, we discuss four talking points from Wednesday night's action
Coman haunts parent club
All eyes will be on Paul Pogba in the French national team this summer, but his compatriot Coman is one of the potential stars of Euro 2016.
The 19-year-old, who is on a two-year loan at Bayern from Juventus but has no clause saying he could not play against his parent club, was superb again on Wednesday night, using his pace and agility on the right wing to devastating effect.
He was rewarded with the last goal, a fine left-footed finish after cutting in from the right, and with an option to buy at the end of the two years, his future looks clear.
Juventus are back in the elite
Before Massimiliano Allegri arrived at Juventus in 2014, the Old Lady hadn't reached the Champions League semi-final for 11 years.
Their runners-up performance last year surprised many, but the preconception that Juventus were 'small underdogs' before the final in Berlin against Barcelona irked many fans.
Juventus were, and are again, an elite side with elite players. They have managed to stave off interest for their prized asset in Paul Pogba and will have to do more of the same in the summer with Paulo Dybala, and the competitiveness of Serie A has most definitely helped their progress.
As Allegri approaches 100 games for Juventus, the lost column reads just 14, and goals against a mere 67.
In the first half against Bayern, they proved they can put in the perfect European away performance, and despite Bayern's might shining through, they are worthy of credit.
Beating Juventus can be a turning point for Pep
Prior to the announcement Guardiola will join Manchester City in the summer, his Bayern side had won 25 of their previous 29 games.
Since then, they had been victorious in only five of nine games going into the second leg against Juventus and cracks were showing for the first time in his reign.
Falling 2-0 down so easily to the Italians left Guardiola's stint at risk of ending with a whimper but the late comeback he engineered was remarkable.
Just as it looked like he had been outdone tactically by Allegri, he made sound substitutions and saw replacements Thiago Alcantara and Coman score decisive goals.
Guardiola is under pressure to deliver a Champions League title before he leaves for England, and beating Juventus can be the spark he needs to do just that.
Cuadrado can have a future at Chelsea
Colombian Cuadrado made a big impact in the first half as he scored one goal, had another wrongly disallowed and hit the post when he should have netted.
While he made just four starts for Chelsea after joining them from Fiorentina 13 months ago, he has been a regular for Juventus since moving on loan in August.
Many Stamford Bridge fans are yet to be convinced the 27-year-old can become more involved at their club when he returns to London at the end of the campaign.
But if Antonio Conte - a man who will have seen plenty of him in his capacity as Italy's manager - is appointed as Chelsea's next boss as expected, there is every chance he'll hand Cuadrado a lifeline.
