Fernandinho believes Gabriel Jesus' pace and passion can give Manchester City's attack the cutting edge they have lacked this season.
Jesus came off the bench during the second half of City's 0-0 draw at Porto on Tuesday, a result that sealed top spot in Champions League Group C.
It was a frustrating outing in front of goal for Pep Guardiola's side, something that has become familiar during a stuttering start that sees them lying 11th in a compressed Premier League table, and City's 18 attempts were their most without scoring in a Champions League match.
