City won on the last day of the season, beating West Ham United at home to raise the trophy for the fourth successive time.
We'll try to go for the double but, right now, I don't focus on that," said Haaland of their FA Cup final against Manchester United on Saturday.
I focus on what we've just achieved and now it's about enjoying that. In a couple of days, let's start focusing on the FA Cup."
On winning, Haaland said: It feels fantastic. So proud and happy for the whole club - it's amazing.
It was a race all the way until the end. All credit to the other teams, they made it really difficult for us, but yet again City and the whole club showed how to do it.
It's truly incredible, this club is incredible. Not everyone understands how hard it is to win one, but for this club to win four in a row is incredible. To be part of it is unreal and I'm so proud.
I celebrate with my family and friends and of course with the whole club. This trophy - for the fourth year in a row - is for the whole club so everybody should celebrate it."
