The pair combined for the 45th-minute opener to finally prize open the battling Saints, who were fighting for their survival against relegation.
Jack Grealish extended City’s lead in the second half before setting up Haaland for a spectacular third as he became the first City player to reach 30 league goals in a season for the Club since Francis Lee in 1971/72.
Sekou Mara pulled a goal back for the Saints before Julian Alvarez added a fourth from the penalty spot after De Bruyne was brought down as we closed the gap on leaders Arsenal.
