Cristiano Ronaldo put the finishing touches Juventus' 3-0 win over Bayer Leverkusen on Tuesday as the Italian club recorded their first win in this season's Champions League group stage.
Ronaldo's goal in the 89th minute was his 127th Champions League goal after earlier strikes from Gonzalo Higuain and Federico Bernardeschi.
The win sent Juve top of Group D on four points, the same number as Atletico Madrid, who beat Lokomotiv Moscow 2-0 away.
The Italian champions had been held 2-2 by the Spaniards at the Wanda Metropolitano in their opener.
"We had a good match against a team who love possession and are not easy to deal with," said Juventus manager Maurizio Sarri.
"They took a lot of energy out of us in the first half. After the break, they slowed down a little and we took control."
Leverkusen face an uphill battle after their shock 2-1 defeat at home against Lokomotiv and are rooted to the foot of the table.
"It was a clear defeat," said Leverkusen manager Peter Bosz. "We played well in the first half even if we didn't have chances, and then we made the mistake which led to the first goal.
"It's the difference between a team who has experience in the Champions League and one that is beginning its journey at this level."
Juventus next host Lokomotiv and Leverkusen travel to Atletico on October 22.
Portuguese teenager Joao Felix said he was "delighted" to score his first Champions League as Atletico secured three points on the road in Russia.
The 19-year-old Felix, Atletico's club-record signing, put the visitors ahead three minutes after half-time in Moscow and helped set up Thomas Partey for the second goal on the hour.
"I'm delighted to score my first Champions League goal. It was a great game, and the important thing was that we came away with the three points," said Felix, who joined Atletico in July for €126 million (Dh506m).
"It was a question of time before the goals started to flow and more will come."
Atletico took the lead here on 48 minutes when Felix stabbed in a rebound after his first effort was parried by Lokomotiv goalkeeper Guilherme Marinato.
Felix, who last season became the youngest player to score a hat-trick in the Europa League while with Benfica, created the second goal with a searing break from deep.
He floated a superb cross-field pass to Diego Costa who laid off into path of Partey to tap home on 58 minutes.
