Rangers manager Philippe Clement tells BBC Sportsound: "We deserved to win, that's clear.
"We know the pitch is not an advantage, but we did it in a good way, no excuses.
"We played our football and could have won by more. If you play a game where you miss a penalty and goals are disallowed it can become tricky, but we had a relaxed afternoon and never came into danger.
"[VAR] is a very important thing for me - there are less mistakes. In general the game is more honest, so I'm a huge favourite of VAR.
"We are going to work hard in the international break - there are a lot of things to do in the club. I'm here to work, not to have free time and enjoy life. My life is football."
