Fernandinho says he's ready to fill in for Aymeric Laporte at centre-back.
The Frenchman suffered a serious knee injury in Saturday's win over Brighton.
"Of course it's not good," he told City's website. "We'll see the news about him, we wish him a speedy recovery and to get well soon because he's an important player for us. It wasn't the way I wanted to come in, but in football these things can happen.
"Whatever the manager needs, I'm ready. It's a different position, a different role now, and we'll see. Getting ready for the next games, I'll try to do my best as always.
"We're going to try and fix it, not to concede the chances we conceded today. For the next games, for the rest of the season. It was good, it was ok."
