City only needed a point to be crowned champions of England for a second time in three years and they finished off the job with a comfortable 2-0 home win over West Ham.
Samir Nasri and Vincent Kompany were on target in a one-sided encounter at the Etihad Stadium, as West Ham were unable to live with City's attacking threat.
Pellegrini's side have been a joy to watch this season and they only missed out on equalling Chelsea's record of 103 Premier League goals in a campaign by one.
He said: "It's not just winning titles that is important, but it's the way you win them.
"It doesn't matter who you play, maybe it's easy to score a goal and then go behind the ball.
"We have players to play on the counter-attack, they are fast and technical, but again, I'm not criticising the way other teams play, but if it was me, I wouldn't be happy to win in that way.
"The fans enjoyed the whole season - we broke the records for the most goals scored by any team in England. It is the way we must play with the quality of players we have.
"Of course I am proud to manage this group of players and this club. It's a great honour to be the first manager from outside of Europe to win the title but I'm not the most important person.
"I think we all enjoyed this season – the players, me, the fans – because the team played very well, this is as important as winning the title.
"I congratulate all of the teams – it was a fabulous Premier League."
