The Brazilian’s most recent appearance came in the 3-1 win over Everton and his return will bring additional strength and protection in front of the back four.
However, Kevin De Bruyne, who only recently returned to fitness after a six-week layoff, is out. David Silva, a substitute at the King Power Stadium, comes in for the Belgian.
Fabian Delph is suspended after his red card in the defeat to Leicester and is replaced at left-back by Oleksandr Zinchenko. Vincent Kompany makes his first start since the win at Watford at the beginning of December.
Long-term injury victims Benjamin Mendy and Claudio Bravo remain on the sidelines.
City team
Starting XI: Ederson, Danilo, Kompany (c), Laporte, Zinchenko, Fernandinho, Silva, Bernardo, Sterling, Mahrez, Aguero
Subs: Muric, Walker, Stones, Sane, Otamendi, Jesus, Foden
Tactics
City, as ever, will play a 4-3-3 formation. Danilo continues at right-back, with Kompany and Aymeric Laporte at the heart of the defence.
Fernandinho will anchor the midfield, while our two Silvas pull the strings just in front of him.
And up top, Riyad Mahrez and Raheem Sterling will provide width, with Sergio Aguero once again the man operating through the middle.
