Real Madrid coach Zinedine Zidane says he's a supporter of video technology after Barcelona's 'ghost goal' on Sunday.

Zidane was asked to comment on the drama between Barca and Valencia when Lionel Messi had a clear goal denied by the match officials during the 1-1 draw.

He said, "I find it odd that video support is not used in Liga. Technology is changing and this system will improve football.

"But Spanish football will decide when. As a fan, I want football to progress.

"It is possible that we lose some uncertainty, spontaneity, but it is inevitable, we are moving towards more technology. There will be less controversy."
