Real Madrid fans have slammed VAR for an error in judgment in the build-up to Man City's equalizer.

Real Madrid fans have been left fuming after a post-match footage revealed that Man City's equaliser should not have stood as the ball went out of play in the build-up to the goal. The Santiago Bernabeu faithful saw their side share give up a crucial lead in a 1-1 draw of Tuesday night's Champions League semi-final first-leg encounter.

It was a match of oddities, with Real Madrid taking the lead in the first half following City's dominance, and the latter getting a leveller in the second half despite the hosts having a better second half. The deadlock was broken in the 36th minute when Vinicius Jr hammered home his seventh goal of the campaign after a brilliant run and assist from Eduardo Camavinga against the run of play.

The second half started on a promising note for Real Madrid but it was Man City who were rewarded for their patience. Kevin De Bruyne levelled for City in the 67th minute with a strike similar to Vinicius'. However, the goal sparked controversy on the field and in the dugout of the host as the ball seemingly went out of play in the build-up of the goal. 

Bernardo Silva had controlled the ball close to the touchline on right flank. However, his touch seemed to have been a tad heavy, forcing the ball to cross line.  Ancelotti, who stood on the edge of his technical area a few meters away from the Portuguese midfielder, quickly signalled to the match officials that the ball had crossed the line but protest yielded no result. With play being continued, Real Madrid won possession but gave it away centrally, giving Jack Grealish and Ilkay Gundogan the chance to combine and set up De Bruyne for the goal.

According to BeIN Sports' 3D technology, the ball went out of the field. Watch:

Meanwhile, Carlo Ancelotti, in his post-match reaction, criticised referee Artur Soares Dias. Having received a booking for protesting the referee's decision on the touchline, the 63-year-old Italian coach reiterated that City's equaliser shouldn't have stood as the images he saw after the goal confirmed that the ball indeed went out of play. 

"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!'

"It was out. It's not me saying it, the technology does," Ancelotti added in his postmatch news conference. "It surprises me. They're small details, but the referee wasn't attentive. The players deserved more cards on the pitch, not [me] off the pitch."
