Manchester United midfielder Nemanja Matic has said star team-mate Paul Pogba needs to "take more responsibility".
Pogba, 25, has been criticised for some of his displays this season, with manager Jose Mourinho unhappy with the midfielder's form at times.
Matic said his team-mate would only get better, but he urged Pogba to deliver more often for United.
"Of course he's still young, he can improve and he will improve and he showed in this game [against City] that he always can play better and better.
"He took responsibility, he scored and give to other players more confidence – after his first goal we started to believe we can do something. It is exactly what he has to do."
Pogba has scored five goals and assisted 10 in 23 Premier League appearances this season.
Matic feels it is obvious just what Pogba can produce, saying: "He is a great player.
"He runs a lot, has quality with the ball, he can score and he can also defend very well."
