Sterling was supersonic against the Saints on Sunday, as he turned the opposition's defenders inside out.
Sterling was outstanding, a constant threat down the flank, and he was delighted that his side took advantage of second-placed Liverpool's draw at Arsenal on Saturday.
He said: "I don't know".
In isolation getting well beaten at the Etihad Stadium is nothing to be desperately ashamed of, even if going down so heavily isn't ideal for a team short in confidence and buoyed recently by good defensive displays and clean sheets. "It is great times at the moment".
Hoedt's own goal gave City a sixth-minute lead, the centre-back - whose initial failed clearance brought about the move - finding his own net when attempting to keep Sane's shot out.
It took a further six minutes for City to double the lead, Bernardo Silva setting free Sterling on the right and the England forward selflessly squaring for Aguero to hammer in from close range.
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.
Mac Miller's Cause of Death Revealed
Rapper Mac Miller's cause of death was revealed on November 5, and coroner's say he died of a mixture of fentanyl and cocaine. Prince died at 57 in April 2016, and a medical examiner ruled it an accidental overdose, finding fentanyl in his system.
However, Sterling would make it 4-1 for the hosts just before the break.
Southampton are in 16th place, two places above the relegation zone with a solitary win this campaign and manager Hughes was left to rue the disastrous start to the game.
"The game was not over, because we conceded". City will always ask questions and have a lot of talent, power and pace. Pep Guardiola can afford to make one or two changes but that doesn't seem to bother them too much and this machine will continue to roll on.
Shakhtar Donetsk manager Paulo Fonseca will be able to call upon the services of key Brazilian duo-Taison and Dentinho and he will need all the quality he can muster to come away with a positive result.
'Every game is important, ' he added. "I like to have that feeling that we won 6-1 and are top but at the same time we have to improve in many situations to be a more stable team because when we arrive in the next steps of the Champions League when you concede in those situations you are out because the level is higher". The scoreline is maybe a bit of a harsh state from our point of view.
The visitors pulled one back with a penalty but it proved a minor setback for City, who again dominated Southampton in the second half.
