The coach backed football's lawmakers to iron out the flaws in the VAR system that marred Chile's 2-0 win over Cameroon
Chile coach Juan Antonio Pizzi felt the use of the Video Assistant Referee (VAR) system affected his side mentally as they struggled to see off Cameroon at the Confederations Cup on Sunday.
The South American champions saw Eduardo Vargas' wonderfully worked goal in first-half injury time chalked off after VAR was implemented, controversially ruling the forward was fractionally offside as he ran on to Arturo Vidal's delightful throughball.
But it came to their aid late on when Vargas did get his goal after VAR overruled the linesman and adjudged Alexis Sanchez to be onside in the build-up.
