Montana feels that Seattle can go on to win multiple titles due to the young players they have on their roster and the setup of their team.
He told NFL Network: "I think they have the capability to. When you look at the way the team is put together, they're young, they're aggressive; their coach is very aggressive and upbeat.
"Anytime you can make going to work fun, even though you're playing as I say 'a stupid game for a living,' it makes going to that facility every day really a joy. When you're having fun at what you're doing, you're always a lot better at it."
Montana won four Super Bowls with the 49ers during his career.
