Gabriel Jesus has settled into life at Manchester City quite quickly and Fernandinho is impressed and expects him to keep improving.
The 19-year-old forward has scored three goals in three appearances since joining from Palmeiras last month.
Jesus has been in spectacular form for City, with Aguero spending the last three matches on the bench.
“He has things to learn, but he is starting very well,” Fernandinho told the club’s official website.
“I am very happy that he is progressing well and with confidence.
“The most important thing is that he is being able to score goals. He adjusted very quickly. The English football is not as easy, so I honestly hope he continues in this level in order to improve even more.
“I am sure he is a player that will develop a lot more and I am absolutely sure that he will be a top-class international player.”
