Celtic manager Brendan Rodgers: "It's a game you don't need to be perfect, you just need to win and we did that by the end. We found an energy and a will and desire to keep pushing.
"Rangers came in with a big motivation. We knew there would be challenges. It's all about the defining moments and we were able to get the winner because of that."
Retiring Celtic goalkeeper Joe Hart: "I've loved every minute of my whole career. Football has been everything to me and it's everything I am as a person. I'll have to find out who I am now.
"I'll miss it one day but right now I have so much joy and thanks to everyone who's made it special for me. I'm super proud. I'm just trying to take it in as best as I can."
Celtic defender Alistair Johnston: "It's in the DNA of this club. You want to win trophies and the fans demand it. We knew going into the last couple of months that we had none on the board but there were two to play for.
"We knew we had the quality there and we've kicked into gear. Big players need to step up and we had some really big performances."
Rangers manager Philippe Clement: "That we didn't score and Celtic scored... I think that was the only difference. Everybody saw it was really close.
"My players played a brave game, a good tactical game. I think much improved from the last Old Firms. It's about decision-making and quality to finish off the actions.
"The mentality is there, the hard work is there, the structure is there and now we need to build on this. We are going to build a new team."
