Goal understands that City lead the race to land Guardiola when he his contract with Bayern Munich expires at the end of the season.
But Toure’s representative, Dimitri Seluk, insists Roberto Mancini should be credited for City’s rise.
“Pep is a great coach. But he has won the title at Barcelona and Bayern Munich,” Seluk told the Sunday Mirror.
“The truth is that my grandfather would win the title with Barcelona and Bayern Munich because they are big clubs with great players.
“Look at Luis Enrique now. Last season he won the title and the Champions League with Barcelona.
“I’m not saying he isn’t a good coach, but look what he did at Roma. Nothing. I’d like to see Pep take a club that is eighth or ninth and make them champions.
“That’s why Roberto Mancini was the best manager City have had.
“Manuel Pellegrini is also a good coach who deserves credit, but Mancini built the team. He took a team that was nowhere and made them champions.”
Seluk is also wary of City’s transfers if Guardiola is appointed and admits it could trigger the end of Toure’s time at the Etihad Stadium.
“In Germany, they say it is 100 per cent that Guardiola will be City’s manager and I believe it also,” said Seluk.
“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.
“He has had offers to leave City, but he loves the club, he loves the fans and he loves the people of Manchester.
“Once Pep comes, there will be a lot more Spanish players arriving.
“They are trying to turn City into Barcelona when they should be creating their own identity.”
