Manchester United midfielder Nemanja Matic insisted he was happy to see the video assistant referee (VAR) system used, but he wants it to be quicker.
A Juan Mata strike was ruled out by VAR during United's 2-0 win over Huddersfield Town in the FA Cup on Saturday, but only after a substantial delay and a technical issue.
Matic, 29, said he wanted the VAR to be part of the game, but the Serbian midfielder was unhappy with how long it took to make the decision.
"We saw the goal and we are not sure it was offside but the referee made a decision and they saw it on TV and we are happy that we scored again and that's it," he said.
