ictory over Huddersfield might have been greater had the video assistant referee (VAR) not chalked off a Juan Mata goal in the first half.
The Spaniard was offside but on-field referee Kevin Friend took more than two minutes to give the decision. Matic says he is in favour of the system but has called on the authorities to speed up the process.
He said: "They have to do it quick, they have to do it in 30 seconds, so after two minutes we are cold and this is the only problem. Other than that I like it.
"We are not sure it was offside but OK, the referee has made a decision, they saw it on TV.
"It was a little bit strange because you have to wait two minutes to see what happened, but it's OK. It's good.
"I like it. I think it will be better for football, they just have to do it a little bit quicker because we waited so long for the decision.
"Two minutes is a long time on the pitch but I think overall it will be good for football.
"It's normal that referees make mistakes every game and they can refer it to TV but it needs to be quicker."
Matic faced Huddersfield without usual midfield partner Paul Pogba, who was ruled out with illness.
The Frenchman is a doubt for the trip to Sevilla this week, although sources have told ESPN FC he trained at Carrington on Sunday to boost his chances.
Matic added: "He is an important player for us, this club, but he is ill.
"I am not sure what has happened, I think he was ill and didn't feel very in the morning so I hope he will be ready for the next game."
