The Blues trailed Arsenal for most of the season and suffered some surprising losses in the first half of the campaign.
However, City began building a head of steam after the World Cup, hunted Arsenal down and finally moved to the summit with a perfectly-timed winning streak that has resulted in a third successive Premier League title.
Arsenal’s 1-0 loss to Nottingham Forest means Pep Guardiola’s side cannot be caught – and Walker, a surprise guest on the Matchday Live champions show – couldn’t be happier.
“It’s been a little of madness in there (first team building), but we’re fully focused for tomorrow,” said Walker.
“We’ll celebrate after tomorrow at some stage, maybe but we have more games coming up.
“I would have loved to have won it tomorrow and go out and beat Chelsea.
“Arsenal pushed us right to the limit they’ve been fantastic, so all credit to them
“We just went on an incredible run, they had a few hiccups and we capitalised on it and we’ve managed to end up where we have now.
“It’s the players we’ve got. We’re a bunch of lads who have achieved so much over the last number of years and we understand the standards we’ve set.
“As for inspiration, there’s the captains, managers and so on but we drive ourselves - we achieved so much over the past five or six years, but we knew the bar wasn’t high enough at the start of the season.
“It wasn’t good enough and when we came back after the World Cup, we had to kick on and fair play to the lads – that Liverpool game kicked it off.
“We wanted to prove anyone doubting us wrong - it wasn’t good enough.
“With the lads we have in the dressing room we always believe we can do something.
“It was the first season where we kept on scoring late goals so until the end, we know we can do it.
“The standards of Premier League have gone up, but this is what this club is built for, certainly that’s how it’s been for the six years I’ve been here, so fair play to everyone involved.”
Asked when will he start enjoying the moment, Walker said: “Tomorrow! I’m glad it’s done and we’re over the line.
“We will play the good football we do for our fans against Chelsea because they deserve it, then we have Brighton and Brentford and then two massive games to hopefully go and make history.
“If we can do well, the handbrake’s off after that!
“You’ve got to be ready at the business end of the season because that’s what this club is all about and what we are built for.”
