Toure started just once in the Premier League in his final season at the Etihad, when he captained the side against Brighton in the penultimate game of the season.
The Spaniard initially did not want to comment on Toure's harsh criticism after the Ivory Coast midfielder suggested that he had treated him less favourably because he is African.
Reacting to Toure's accusations, the City boss told Catalan station TV3: "They were lies and he knows it".
"We were together two years and it is only now when he says it. He never told me face-to-face". I don't know why but I have the impression that he was jealous, he took me for a rival.
Guardiola has since come out to hit back at Toure's claims.
Amazon buys rights to 20 Premier League games a season
It's the first time a digital streaming provider has won the rights to show Premier League matches in the United Kingdom. In contrast, the Premier League will be delighted with this outcome after having secured a leading online giant.
That, of course, opens the door to a potential cross-city move for Toure, who could join United and work under Jose Mourinho. "When you see the problems [Pep] has often had with African players, everywhere he has been, I ask myself questions".
"You know, Guardiola can not be called a dog", he told Sport24. I've been out of Barcelona for six years. He'll never admit it [not liking Africans].
Guardiola also found time to talk about returning to Barcelona in the future. "I am not the same, nor do they even look at me in the same way", he said.
"It was a generation of brutal players and the best player in the world [Lionel Messi]".
Such is the ill-feeling between Toure and Guardiola, Seluk says that the Ivorian would be willing to play for any top-six club next season with a weekly wage of £1, supplemented by selected bonuses.
