Marquez was given yellow for the takedown, as he kicked Silva’s knee. The new AC Milan attacker took the pen with Cristiano Ronaldo away from the team, but Guillermo Ochoa dove low and right to slap the ball wide of the frame.
Portugal then headed the ensuing corner over the frame, and the match remained scoreless in the 18th minute. This was VAR at its best. though there are plenty of counter examples from this 2017 Confederations Cup.
