Rangers manager Philippe Clement: "The boys get the reward they deserved, what they did not get in the last few weeks.
"Things were not on our side. Even with injuries and changing a lot, everyone in the squad is working hard to get better and better. This is proof of that. We need to continue like this for the next couple of months.
"It is a very important win. It gives belief to everyone following Rangers. This new squad is building, there is a lot of potential in it and we will work hard to make it better. That is my job to do, and my mission, also."
Celtic manager Brendan Rodgers: "Rangers were the better team. We were not aggressive enough without the ball. On the ball, it was far too slow.
"I'm not sure if the 14-point gap took the edge off, it shouldn't, but maybe subconsciously it can do. We did not play well and Rangers deserved to win.
"It was one of those days. They are not robots. The energy in the stadium, they wanted to prove a point, they hadn't beaten us and they are so far behind in the league, so there are many reasons why."
