Pep Guardiola recently insisted that Yaya Toure's agent must apologise or else the African star will never play for him again. Now, the Manchester City midfielder's representative has hit back at the Spaniard, saying he is ready for "war".
Dimitri Seluk has been very outspoken about Toure's struggles at City this season, a fact that has seemingly upset Guardiola.
After the 45-year-old coach left the four-time African Player of the Year out of the Citizens' UEFA Champions League squad, Seluk slammed Guardiola for "humiliating" his client.
However, on Tuesday, Guardiola struck back, insisting that Toure won't play for him again unless his agent apologises for his remarks.
"If Pep Guardiola wants a war, then he can have one," Seluk told the Daily Mirror in response to Guardiola's strange request.
"Pep didn't like my opinion? But what does he expect me to say when he does this to Yaya?
"Yaya is a player who has made history for Manchester City. He has won the Premier League twice, he has won the FA Cup, he has won the League Cup twice and he helped them reach the semi-finals of the Champions League for the first time.
"I spoke out because I felt that Pep was being vindictive to Yaya.
"Unfortunately for Pep, we live in a world where you have the right to free speech. He has reacted to what I have said about him by punishing Yaya again. But I'm not surprised. Pep doesn't want players with personality. He only wants players who are scared of him and will do what he says.
"The first thing he did when he arrived at City was to pick a fight with Yaya and Joe Hart, two of the club's biggest players. Hart is England's goalkeeper; Yaya has won the African Footballer of the Year four times.
"They have both been big personalities in the dressing room at City, and Guardiola doesn't like that.
"Will I apologise? Well, I have learned that you must never say never.
"But will Pep apologise to Yaya? Will he apologise to Joe Hart or Manuel Pellegrini?
"Look what Guardiola did to Pellegrini. He took his job when he was still fighting for titles.
"Colleagues should have respect for each other, especially in England, where it is important to act like a gentleman.
"When you first go into someone's house, then you should treat them with respect. You don't go into someone's house and ask them to leave.
"He was the same at Barcelona. He forced Samuel Eto'o to leave the club. Zlatan Ibrahimovic, a player who cost £57 million, was sold for just £18 million.
"It has to always be about Pep Guardiola, no one else."
Toure, who announced his retirement from international football on Tuesday, is yet to respond to Guardiola's explanation as to why he has been axed from the squad.
