The Man City striker scored his sixth Premier League hat-trick as Watford were blown away at Vicarage Road.
Aguero is now three goals away from breaking Eric Brook's long standing record of 177 goals for the club. "Hopefully that will happen very soon, and hopefully we can have a big celebration," Guardiola said.
Harry Kane, Wayne Rooney and Luis Suarez have also scored six Premier League hat-tricks and only four other players have more.
