Sarri: Why CR7 was angry with sub

UEFA Champions League

Juventus manager Maurizio Sarri has commented on Cristiano Ronaldo's outburst after being substituted in the UEFA Champions League for the first time in three years.

The Portugal international cut a frustrated figure after failing to find the back of the net against Lokomotiv Moscow, while teammate Aaron Ramsey also 'stole' the forward's third-minute opener.

Ronaldo's free-kick was fumbled by goalkeeper Guilherme, and as the ball appeared to be crossing the line, the former Arsenal midfielder tapped it in to claim the strike.

Had the goal been awarded to Ronaldo, he would have set a new Champions League record by scoring against a 34th different club.

Speaking after the game, Sarri played down Ronaldo's reaction to being taken off while the score was still at 1-1 – the first time the Portuguese superstar failed to finish 90 minutes in the competition since February 2016.

"Ronaldo was angry because he wasn't very well, he had a knee problem a few days ago and his adductor got tired," Sarri said, as per CNN.

"At the end of the first half, he was nervous. I was afraid he would hurt himself and I preferred to take him off."

Douglas Costa went on to score a late winner as Juve moved to the summit of Group D ahead of Atletico Madrid.
