"I spoke ten times about this, you know my opinion. I cannot answer at every press conference about Aguero, He is so happy, so are we," said Guardiola at a press conference on Friday ahead of Sunday's English Premier League (EPL) match against bottom side Sunderland, reports Xinhua news agency.
Aguero said on Thursday that the club is yet to speak to him about where his future lies, saying, "It is one thing for the club to say it and another to tell me."
"I always said in June it will be seen," he said. "The club can say what it wants but in June they will have to meet with me.
"My intention is to stay but it is a long way away. I have three months to give my best and hopefully we can achieve some title."
The 28-year-old has been dropped several times this season.
