Bayern Munich manager Carlo Ancelotti has called for video technology to be introduced in football after his side were controversially eliminated from the Champions League by Real Madrid on Tuesday.

The Bundesliga side went into their quarter-final second-leg fixture trailing Real 2-1. Bayern hit back and forced the match into extra time at the Bernabeu, but Arturo Vidal was shown his marching orders for a second yellow when he appeared to have won the ball instead of conceding a foul.

Meanwhile, Cristiano Ronaldo put his side ahead in the 104th-minute of extra time, but the Portuguese forward appeared to have been in an offside position before finding the back of the net.

The 57-year-old manager says he feels that video technology is necessary for football.

‘We had thought of everything going into this game – except the referee. It’s a pity because it was the perfect game otherwise,’ Ancelotti told Mediaset Premium.

‘I am very proud of my players, as they did all they could and more, but then it went the way it went … The referee probably wasn’t up to the task.

‘I don’t think Real Madrid have any influence on referees. The officials tonight simply got it wrong. I had never been in favour of VAR technology, but I must admit it’s necessary now.

‘You can’t decide a Champions League semi-final spot like this. I spoke to [Zinedine] Zidane after the game, and he agreed with me that the refereeing performance was negative,’ he added. ‘It shouldn’t be happening at this level and I hope the referees will be helped by technology as soon as possible.’

Madrid went on to win the match 6-3 on aggregate to book their place in the semi-finals of the Champions League.
