Fernandinho has warned that new striker Gabriel Jesus must be given time to settle despite making a spectacular start to his Manchester City career.
Jesus, 19, has scored three times in his two Premier League starts, since completing a £27 million move from Palmeiras, including an injury-time winner in City's 2-1 win over Swansea City on Sunday.
His brilliant form has led to suggestions that he is set to permanently oust Sergio Aguero as City's first-choice striker.
Brazil and City teammate Fernandinho is delighted with Jesus' impact but has warned that the teenager cannot be expected to replicate his form for the rest of the season.
