Juventus suffered a shock defeat against Lyon on Wednesday night.
The Serie A champions were expected to cruise past their French hosts at Groupama Stadium but were undone by Lucas Tousart's first-half goal.
Houssem Aouar did well on the left wing before driving into the box and cutting back for his teammate, who beat Wojciech Szczesny at his near post from six yards.
Despite their best efforts, Juventus failed to get back into the game and now need to turn the tie around in the second leg next month.
This was one of those rare occasions where Cristiano Ronaldo failed to bail his side out in the Champions League.

He would have no doubt been annoyed with his teammates for their sub-par performances and it seems he took some of that frustration out on a pitch invader.
While the game was still going on, a young supporter broke onto the pitch and approached Ronaldo.
Normally, the Portuguese superstar is good in these situations, but this time, he pushed the fan away and appeared very angry with the disturbance. Check out a clip below:
Let's be honest, very few people will have an issue with how Ronaldo handled that.
He's performing on the biggest stage, trying to inspire Juventus to get back into the match - their most important of the season so far - only to have his concentration broken by a pitch invader.
The steward slipping at his feet probably didn't help the situation either.
Eventually, the fan is dragged off the pitch and the game continues, but it's clear Ronaldo was very annoyed with the stunt.
All future pitch invaders should be aware: Do NOT approach Ronaldo in the middle of a massive Champions League fixture.
