It was unlikely that City were ever going to need much help seeing off Saints, but Wesley Hoedt charitably gave them an early advantage as he turned into his own goal with just six minutes played. That's an average of three goals per league game and if they continue at that rate they will end the season having scored 114 league goals, eight more than they managed previous year, in what was a record goalscoring season for the Premier League.
Aguero etched his name into history after finding the back of the net during City's league clash against Southampton on Sunday.
It may be harsh to single out one Southampton defender given they were all dire, but Hoedt arguably endured the most hard outing, haplessly giving City the lead.
The Manchester City manager was recognised for his side's Premier League title last season and the club are again setting the pace this season, with nine wins in 11 games.
It appeared City were capable of scoring nearly at will and a slick move saw them make it three in the 18th minute.
Sane, Sterling, Silva and Aguero can be seen passing the ball amongst themselves inside the Southampton area before, eventually, losing it.
Sane's goal was his third of the season and his second in three Premier League matches, but he admitted there was an element of luck involved. "Maybe one day they don't score, and then the team doesn't score at all".
However there was never a hint that Southampton might be able to launch anything resembling a fightback and City ended the half as they had begun it - by scoring.
"Leroy is always a man who looks up for me", said Sterling.
Guardiola believes Sterling will add to his astonishing haul of 46 caps, but feels he has room to improve at the age of 23 in his bid to be rated among the world's finest players. "It's fun to play with this team".
