"If you get a little taste of being a number one you just want to keep doing that and you want more and more and more."
Sinisalo compared this drive directly to the persistent ambition required to win sequential trophies.

You never get bored of it."
He acknowledged the unique scrutiny placed on a Celtic goalkeeper due to the visible nature of any errors.
"There's always a lot of pressure as a Celtic player but even more as a goalie because eyes are on you and every little mistake is obviously vital."
Sinisalo concluded that he accepts the responsibilities of the role as part of his ongoing growth.
"I've chosen my position so I very much understand that and I accept that. I'm still growing, I'm trying to get better every day."
Speaking further about the senior leadership, Sinisalo praised the core group for helping secure the league title.
"We as a group were really lucky to have a lot of winners in the changing room, people that are leaders."
