"It's a big strength for us that anyone can score the goals, and we have that hunger".
"That won't happen at all", he added, when asked if a move to United might occur in the future.
"I like to have that feeling that we have won 6-1, we are top of the table, we are satisfied again with the performance and how they fought until the last minute, but at the same time I have the feeling that we have improve in many many situations to be a stable team."
The 23-year-old has improved hugely since the arrival of Guardiola but the City boss says the players deserve the credit for their willingness to learn.
His late goal against the Saints moved him level with David Silva and Bernardo Silva on three goals, though he is still behind Riyad Mahrez, who has four, Raheem Sterling, who has six, and Sergio Aguero, who has seven. I have the feeling he is now enjoying scoring goals and making assists and be important in winning games.
If you feel you are in somewhat of a no-win situation against City, then that is not the case for the next two games for Saints which have taken on great significance. The English attacker has been in very good form, and played one of the best matches of his career in the win.
"Still hes loses simple balls, like the Tottenham game when he made an wonderful assist in the first few minutes but then lost a lot of balls".
In the other Sunday game, Chelsea thumped Crystal Palace 3-1 in the London Derby at Stamford Bridge, Chelsea.
Sterling unselfishly squared for Sane in second-half stoppage time to allow the Germany global to score City's sixth, and he said the winger often does the same in return.
And Pep Guardiola's side were never going to pass up that opportunity, were they? "The boys started really well and we were fantastic without the ball, not just with the ball".
"We concede a lot of corner kicks and with the best taker in the league like Southampton had [James Ward-Prowse]".
