Yaya Toure's agent has claimed that Pep Guardiola is overrated as a manager and suggested that the Spaniard's reported summer arrival at Manchester City would harm his player's future.
Guardiola said last month that he was leaving Bayern Munich at the end of the season and has since admitted that he wants to manage in the Premier League.
City are odds-on to be his next destination, but Toure's agent Dimitri Seluk does not believe that it would be a wise move.
He told the Sunday Mirror: "Pep is a great coach, but he has won the title at Barcelona and Bayern Munich.
"The truth is that my grandfather would win the title with Barcelona and Bayern Munich because they are big clubs with great players.
"I'd like to see Pep take a club that is eighth or ninth and make them champions."
Guardiola sold Toure to City when he was in charge of Barcelona in 2010, and Seluk said that both he and Toure do not want him to take over at the Etihad Stadium.
Seluk added: "I don't know what Guardiola's plans are, but - after what happened at Barcelona - of course it is a worry that when he comes Yaya will be out.
"I hope not and Yaya hopes not."
Toure, 32, has a year-and-a-half left on his City contract.
