“Defensively, we have been unbelievable the whole season and we have hardly conceded a goal.
“Offensively, we have been getting better and we scored five beautiful goals against Dundee on Friday night.
“We have worked so hard for this and, finally, we are there and can start thinking of next season. There is always high pressure here and I put high demands on myself as well.
“Today we just have to enjoy it and be happy that we are champions. I’m happy with a lot of the work we have done and we are going to enjoy this night and show we are champions next Sunday.”
Parkhead skipper Scott Brown added: “It’s been a great season for all the lads.
“We started off quite sloppy under a new manager, but we’ve just kicked on and gone from strength to strength.
“Everyone was talking about Aberdeen catching us, but we’ve been under no pressure and we just had to keep winning and that’s what we’ve done.
“We’ve showed our class on the pitch and we’ve played great football at points as well. This squad is just getting stronger and stronger.
“The manager wants to play football and we enjoy that. I think the fans are enjoying that, too, because they’re coming out in their thousands week in, week out.”
Chief executive Peter Lawwell praised Deila and said: “We are the champions and I’m absolutely delighted for everyone at the club – Ronny, his backroom staff, the supporters, the players.
