Celtic secured their sixth consecutive Scottish Premiership title with eight matches left after beating Hearts 5-0 at Tynecastle on Sunday.
Brendan Rodgers' side needed to beat Hearts to become champions after Aberdeen delayed the title win by beating Dundee on Friday.
Celtic are unbeaten so far this season and have dropped just four points so far during this season.
"My job when I came in was to win it in the best way we possibly could," said Rodgers.
"We have had many outstanding performances, but we have only just begun because there's still an awful lot of development in this team. That's the real exciting part."
