He toasted his staff at a post-match news conference following his side's 0-0 draw with Huddersfield Town and warned his players that team's would be even more motivated to beat them next season.
Two more followed in successive seasons before he moved to Bayern Munich, who won three consecutive Bundesliga titles under his management. Today we saw it.
"We are delighted with what we have done and the way we have done it", Guardiola told BBC Radio 5 live.
"You never know you are going to win but I didn't have doubts about what we tried to do". "You win or lose, you have to try and do what you believe". Maybe we will be a little bit relaxed and you have to be focused if you want to maintain what we have done this season. "Back to back in this league will be tough but we accept the challenge".
Pep Guardiola's side had been confirmed as champions on April 15, when rivals Manchester United fell to a shock defeat at the hands of West Brom, but they had to wait until after their penultimate home game of the season to celebrate properly. Supporters were issued with blue and white flags to greet the champions as they were given yet another guard of honour on their way onto the field before kick-off.

David Silva looked certain to score when clean through after just five minutes, only to be denied by Jonas Lossl, and the Huddersfield goalkeeper also saved well when Kevin De Bruyne drove a left-foot shot straight into his chest.
City started brightly, with Christopher Schindler clearing off his line from a scramble at a Leroy Sane corner, but otherwise Huddersfield defended manfully and substitute Scott Malone might even have snatched a dramatic injury-time victor for the visitors.
A strong showing from the struggling visitors earned a valuable point, which may be enough to keep them in the league next season.
