"The video match officials will be in front of the television sweating with the stress, it's not possible to go there like a clerk with shirt, tie and jacket," he said. "They are doing something stressful and that's why we want them wearing the dress code."

For the first time at a World Cup, VAR will be implemented in every game, meaning that the main referee will have somewhere to turn with contentious decisions. Fans in the stadium will be kept abreast of what's going on via replays and messages on big screens.

In theory, this will prevent errors like Frank Lampard's heartbreaking disallowed goal against Germany in 2006.
