Jose Mourinho said VAR is bad for the "beautiful game" after watching Tottenham lose at Sheffield United on Thursday, and expressed his belief that "the referee should be the man on the pitch".
Spurs suffered their 11th defeat of the season at Bramall Lane, as the Blades ran out deserved 3-1 winners thanks to goals from Sander Berge, Lys Mousset and Oli McBurnie.
Berge opened the scoring on the half-hour mark, but Harry Kane appeared to hit an equaliser two minutes later after a dizzying run from Lucas Moura.
