He ruptured cruciate ligaments in his knee in a game against Crystal Palace in 2017, which saw him miss seven months of City's Centurions campaign.
And a tear to the meniscus in his left knee in the 3-1 win over Manchester United in November 2018 meant he played just four more times before the end of the season.
"It's a very, very good feeling," he said. “It was not easy. I am not crying, nothing changed.
“I worked very hard in Barcelona and Manchester [during the rehabilitation period]. All the physios helped me a lot.
“I was injured, came back, then was injured. The fans can be sad, I can understand, but I can do nothing more than work hard.
“I listened to the doctor and I worked on my knee.
“Now I hope everything is good and I can give everything to this club for a very, very long time."
