Liverpool qualified for the Champions League at the expense of Chelsea, Swansea was relegated, and champion Manchester City made it to 100 points as the loose ends were tied up on the final day of the Premier League season on Sunday.
Are Man City the best team England has ever seen? .
"It was lovely", De Bruyne said.
56' - CHANCE! Silva miscues a shot but reacts quickly and is able to cross to an unmarked Fernandinho, who blazes a volley over from next to the penalty spot. His attempt looped over Southampton keeper Alex McCarthy and into the far post netting.
There was never much chance of that but City's thrilling season was capped by another piece of individual brilliance, with Gabriel Jesus producing a superb lobbed victor in the 94th minute to spark wild celebrations.
City have set competition records for wins, goals scored and points acquired during their march to glory in 2017-18, although little of their usual panache was in evidence during a listless opening half at St Mary's.
It is one of several records City have collected this year.
On yet another last-gasp win, he added: "We did it all season, don't surrender, don't give up".
Southampton had appeared comfortable in both securing their survival and holding City to a rare goalless draw until the match entered injury time but, with seconds remaining, Pep Guardiola's near ideal Premier League season was completed in style.
Guardiola's side's goal difference of +79 eclipses the previous record of +71.
They also broke the league record for the most wins in a single season - 31.
De Bruyne ends the season with a league-leading 16 assists.
