The first contentious moment of PSG vs Real Madrid arrived in the 17th minute.
Ronaldo and Dani Alves duel
Cristiano Ronaldo appealed for a penalty after falling under the challenge of Dani Alves, his old adversary from Barcelona.
The move started with Lucas Vázquez in possession on the left flank. After a one-two with Ronaldo, Lucas looked for his team-mate once again. As Ronaldo burst through the PSG defence, he went down under pressure from Dani Alves. Felix Brych - the German referee - waved play on.
Earlier on in the match, Ronaldo was lucky to avoid further punishment after a petulant off-the-ball kick at Alves.
