Iker Casillas has defended his area in over 1,000 matches of professional football, yet his suggestion on how to improve VAR is a little outside the box.
The ex-Real Madrid and Spain goalkeeper feels that the team of referees who run the rule over the big decisions should be accompanied by a former professional footballer to provide an expert perspective.
"I propose that for VAR, as well as the official who analyses the images, there is also an ex-footballer," he told his Twitter followers.
"It would be good [for them] to give their opinion on the incidents that take place during a match," he wrote.
