Manchester City have won a third Premier League title in four years after closest challengers Manchester United were beaten by Leicester City.
It is the seventh time City have finished top of the English football pyramid and the fifth in nine years.
"This has been a season and a Premier League title like no other," said Guardiola.
"This was the hardest one. We will always remember this season for the way we won. I am so proud to be the manager here and of this group of players.
"They are so special. To come through this season, with all the restrictions and difficulties we've faced - and show the consistency we have is remarkable.
