The Ivorian struggled for regular starts under the Spaniard over the last two years and has now been released by the club.
Seluk says the Ivorian has lucrative offers overseas but wants to stay in the Premier League and is willing to join another big club on an incentivised deal to show the world he's still capable of playing at the highest level.
"There had already been some tensions", said Toure, who added that he was now taking responsibility for "being the one who smashed the myth of Guardiola".
Toure also said the former Bayern Munich coach denied him of an appropriate farewell to City.
"He is full of energy and wants to play this season in England".
Toure said: "I do not know why but I have the impression that he was jealous, he took me for a rival".
However, the Ivory Coast worldwide fell out-of-favour following Pep Guardiola's arrival two years ago and he started just 1 Premier League game last season as City marched to the title. As if I made him a little shade. "I'm sure he's still strong enough to play three or four years at the highest level".
De Bruyne was widely viewed as City's star performer in their record-breaking run to the Premier League title and believes there might have been far less conspiratorial reasons for his team-mate looking on from the sidelines. I would have liked to leave with emotion from this club as did [Andres] Iniesta [at Barcelona] or [Gianluigi] Buffon [Juventus]. I came to wonder if it was not because of my color.
"Maybe us Africans aren't always treated the same by certain people".
Toure made over 300 appearances and scored 79 times in all competitions for City since joining from Barca in 2010.
"I am not the first to talk about these differences in treatment".
