VAR denies Ajax goal in Real Madrid Champions League clash

Ajax defender Nicolas Tagliafico appeared to have headed the Dutch side ahead on 38 minutes, but referee Damir Skomina disallowed the goal after Dusan Tadic was shown to be offside on replays. Tadic was deemed to be interfering with Real goalkeeper Thibaut Courtois after the Belgian spilled a header at a corner and Tagliafico nodded in the rebound.

The system, widely used during last year's FIFA World Cup, and now called upon in most of Europe's leading leagues, is making its Champions League debut after it was introduced for this season's knockout stages. VAR was initially set to be rolled out in the Champions League from the start of next season, but the decision to bring forward its use follows lobbying from top European clubs.
