Yaya Toure openly questioned whether Pep Guardiola has a bias against players from Africa.

Toure hit out at his former coach in an interview to be published on Tuesday with the title, "Yaya Toure: 'I want to be the one who destroys the Guardiola myth.'"

"He was cruel towards me," Toure said in excerpts released on Monday. "Do you really think that he would have been able to do that with [Andres] Iniesta at Barcelona? It reached the point where I asked myself if it was because of my colour.

"I am not the first, either. Other Barca players asked the question too. It may be that we Africans are not always treated the same by certain people. When you realize that [Guardiola] has often had problems with Africans wherever he has been, I ask myself questions..."

Asked if he thought Guardiola had problems with players of color, Toure said: "He pretends not to have -- he is too intelligent. He will never admit it. However, the day he fields a team with five Africans, non-naturalized, I promise that I will send him a cake!"

Toure previously played for Guardiola at Barcelona from 2008 until 2010 before reuniting in 2016 at Manchester City.
