Sterling scored twice, taking him to 50 City goals, and added two assists to cap off a week in which he verbally agreed a new five-year deal with the reigning champions. He is becoming a winning player and he is just 23 years old. He is stable and is focused on what he has to do to become a better player.
"He is incredible, sharp, fast, clever, fighting, ambitious, decisive, can play on both sides, in the middle, receive ball behind lines.an Incredible performance - with and without the ball". "We spoke about that in training and said try to score goals". That's true but despite that it's incredible the people I'm working with and I'm a lucky guy to be here.
Guardiola stopped short of saying he should be considered one of the world's best players, suggesting that Sterling is still accident prone in possession at times.
Meanwhile, Chelsea moved second in the table as two goals from Alvaro Morata and another from Pedro saw them 3-1 winners over Crystal Palace.
Six minutes later and City were 2-0 up after Bernardo Silva fed Sterling on the right and the England winger's low cross was slotted home from close range by Sergio Aguero, the Argentine's 17th goal in his last 13 home games.

It's part and parcel of the job. "Thankfully, I'm back on the pitch and the fitter I get the more chances I'm sure I'll get". After a disappointing first season with the club, the Icelandic global has had a bounce-back season.
And Pep Guardiola's side were never going to pass up that opportunity, were they?
He said, "We played with the ball so good but not without the ball".
"The game was not over, because we conceded".
City scored a fourth in first-half stoppage time after Aguero had robbed Cedric Soares as the Southampton defender was attempting to usher the ball out for a corner. "If at the end of our period here, we feel they are better [then that] is enough".
Although fulsome in his praise of the maturing centre-back pairing Aymeric Laporte and John Stones, Guardiola's defensive philosophy is dependent on a team effort to keep the ball as far away from City's goal as possible.
