However, he did not shut down the possibility completely, tempering his assertion with the often-heard maxim that it is impossible to know what will happen in football, per Goal's Sam Lee:
Aguero, 29, has enjoyed an excellent season, netting 21 goals in 25 appearances during City's record-breaking title-winning campaign.
The Argentina international's contract at the Etihad Stadium runs until 2020, and he revealed in March that he plans to honour the deal before he returns to boyhood club Independiente, per Fox Sports (h/t Stuart Brennan in the Manchester Evening News).
Recently, though, he has emerged as a target for Atleti as they look to find a replacement for Antoine Griezmann, who is likely to leave for Barcelona in the summer, per Adrian Gomez of Marca.
Despite his remarkable scoring record at City, Aguero has never been guaranteed a first-team spot under Guardiola, who often seems to favour Gabriel Jesus.
It is clear the former Barcelona manager is not eager to see him depart, though, and it would be a surprise if a deal were agreed.
