Paul Pogba, who has failed to impress at Manchester United so far, must learn from African superstar Yaya Toure, according to a Premier League legend.
The 23-year-old has made three appearances for United since completing a world record move from Juventus in August, but has disappointed in Jose Mourinho's central midfield.
Liverpool legend Jamie Carragher has insisted that Pogba should learn from Toure, who dominated City's midfield in his prime.
"(United) signed (Pogba) to become the game's dominant midfielder, an all-action hero. The barometers Pogba will be measured against in the future are Steven Gerrard, Frank Lampard and Yaya Toure, three of the Premier League's most dominant midfield figures; they scored goals, provided assists, won games on their own and propelled their teams to trophies," Carragher wrote in his Daily Mail column.
"Toure, once he had settled into the Premier League's rhythm, did have a huge impact but, in later years, he left Manchester City's defence wide open and that is exactly what Pogba did to United seven days ago.
"When the goals and assists dry up, that is when the problems start for these players. Conte replaced Fabregas with N'Golo Kante when he arrived because he wanted security, while Toure has been banished by Pep Guardiola."
Carragher also questioned whether Mourinho's current tactics are getting the best out of Pogba.
"From what I have seen so far, (Pogba) doesn't have the tactical awareness to play in a pair in midfield," he added.
"Mourinho will know that better than anyone now. To get the best out of Pogba, there has to be change.
"But should a manager have to change to fit in one player? If they cost £90 million, then the answer is 'yes'."
United's next match is against Northampton in the League Cup on Wednesday night, before they host Premier League champions Leicester City on Saturday.
