Shortly after the referee blew for full time, the Portuguese star uploaded a photo to social media of the game together with an emotional piece of text.
"My return to Old Trafford was just a brief reminder of why this stadium is known as the Theater of Dreams. For me, it has always been a magical place where you can achieve everything you set your mind into," Ronaldo said.
Afterwards, he also had a message for the fans and his teammates as a way of showing his commitment to the club: "Along will all my teammates and with the amazing support that we always get from the stands, we face the road ahead with confidence. Proud to be back at Man United, but above all, happy to help the team!," he concluded.
