Gabriel Jesus is ready to put what he has learned from Sergio Aguero into practice as he takes his place in the Manchester City side.
Premier League champions City will be without their record goalscorer Aguero in the coming weeks after the Argentina striker suffered a thigh injury at the weekend.
His absence will mean an opportunity for Brazil international Jesus, who has largely been kept in the wings by the brilliance of Aguero this season.
With Aguero sidelined until after the derby against Manchester United on December 7, that will start with Tuesday's Champions League clash at home to Shakhtar Donetsk.
"Of course we are going to miss Sergio because we need him and unfortunately we've had a lot of problems this season with injuries – big ones with Leroy (Sane) and (Aymeric) Laporte.
"But meanwhile we have Gabriel and (Raheem) Sterling, who can play in that position, so we are going to live without him for a while."
Avoiding defeat against Shakhtar will see City book their place in the last 16 for a seventh consecutive season.
Guardiola said: "The position we have is good, we have 10 points, but we are not qualified. We have to do our best to go to Zagreb (for the last game) with the job done and that's what we'll try to do."
