Roberto Mancini says Manchester City's title win was "fantastic for the club and supporters after 44 years".
The Citizens clinched the Premier League title after a nail-biting 3-2 victory over Queens Park Rangers at the Etihad Stadium on Sunday.
Manchester United looked like they were going to win their 20th title as City were still 2-1 down after 90 minutes, but were saved by two late goals from Bosnian Edin Dzeko and Argentinian striker Sergio Aguero in the fourth minute of injury-time.
The Italian explained how his side were worthy of the win: "It was incredible - they deserved this.
"To win it like this is incredible. I don't think I've ever seen a finale like this. We didn't deserve to lose, we had a lot of chances and we deserved to win the game and championship."
Mancini now hopes for more success and trophies at the club and is looking forward to a long rivalry with Sir Alex Ferguson, even though rumours of his retirement continue to circulate.
Ferguson has previously said that the rivalry between neighbours has made him feel younger than his 70 years.
"I think for us it was really important to start winning this championship, Manchester City can have a big future now," added the City manager.
Mancini is bound to already have his eye on the Champions League trophy.
