Carlo Ancelotti criticised referee Artur Soares Dias after Real Madrid's 1-1 draw with Manchester City in their Champions League semifinal first leg on Tuesday, saying City's equaliser shouldn't have stood.

Kevin De Bruyne levelled for City in the 67th minute at the Santiago Bernabeu -- after Vinicius Junior had put Madrid ahead with a stunning goal in the first half -- to leave the tie open ahead of the second leg at the Etihad Stadium on May 17.

Ancelotti said he had seen TV images that showed the ball had gone out of play on the near touchline, seconds before De Bruyne's goal.

"It looked like [the ball] was out," Ancelotti told Movistar. "And before that, there was a corner which [the referee] didn't give. The referee wasn't very attentive. He gave me a yellow card, and I said, 'Give them on the pitch, not off it!'
