The striker came off the bench in the Champions League final to play his last game for manchester city
Sergio Aguero’s contract will not be renewed but he leaves the Etihad as City’s all-time leading goalscorer following a hugely successful decade.
Initially, he struggled to establish himself after Guardiola arrived with Gabriel Jesus preferred, but he quickly became the club’s leading light in attack once more.
Despite that, his brother, Mauricio del Castillo, believes the Catalan “had never wanted” Aguero at the Etihad.
He made his comment in a tweet he later deleted, writing: “Guardiola never wanted my brother since his arrival at City.”
When asked why he deleted the message he replied: “Many toxic people, too many.”
He then added: “Perfect, I’m glad people have seen it and I’ll write it again if I want.”
Despite his thoughts, Guardiola has been particularly emotional regarding Aguero’s departure and was reduced to tears on his final Premier League appearance.
“We love him so much,” he said.
“He’s a special person. He’s so nice. He helped me a lot … We cannot replace him, we cannot. There are many players in this club – Joe Hart, David Silva [are others] – who helped us to be this club. We have his legacy. He showed his quality in 30 minutes.”
He also said previously: “Sergio is irreplaceable. I could say in terms of numbers he could be replaceable but it’s not easy. When you see around 360 games and more than 250 goals, the number of titles.
“He’s a legend, the best striker I ever had at this club… but he’s irreplaceable in the mind for our fans, to our people, and to the players that played alongside him or the manager who worked with him.
“A fantastic person and human being. I think if his mind is still aggressive like he is, he can stand his career longer for two, three, four, or five years.
“Many, many players helped this team to take a step forward and of course he was one of them.
“When he came here the club was at one level and he helped put the club at a higher level and that’s why all the people and the fans are grateful.”
