A late Hector Herrera goal ensured Atletico Madrid came back from two goals down to deny Juventus three points with identical headers in a game of two halves.
The game was of more significance for the host as they were sent packing by Juventus from the round of 16 last season means the match sets the pace for what to expect in the group.
Atletico Madrid welcomes Juventus, same team that defeated them at the round of 16 in a game Ronaldo dominated with an hat-trick of last season.
All eyes was on Cristiano Ronaldo based on his goal scoring record against Atletico Madrid in recent games.
It was youngster, João Félix that gave a hint of what to expect from him as he surges at the back line, darts slightly to the right of the penalty area and thuds a low shot at Szczęsny’s far post, which the keeper palms behind.
Cristiano Ronaldo made his intent known with a right footed shot from long range on the left but it was saved.
Coming into into the game, Maurizzio Sarri made a surprising addition to the starting 11, bringing in Juan Cuadrado for injured Bernadeshi against the expectation of having Paulo Dybala and that change came through for the former Chelsea coach.
3 minutes after the resumption, Juan Cuadrado unleashed a left footed shot to the top left corner to get the old lady of Turin going the game.
Blaise Matudi doubled Juventus lead in the game as he heads home from close range off a cross from Alex Sandro from the left flank.
Stefan Savic gave Atletico a route back into the game as he headed home from close range.
Koke’s free-kick from distance, hit from a central position, travelled deep to the far post on the left, where Giménez – repeatedly dangerous in the penalty area nods the ball back into the path of Savić right in front of goal, who buries the chance.
Héctor Herrera completed the comeback for the host with another header from the centre of the box to the bottom right corner off a corner kick from Kieran Trippier.
