Bernardo Silva’s first-half double had us in control of the tie at the interval at the Etihad Stadium.
Goals after the break from Manual Akanji and Julian Alvarez rounded off a complete display from Pep Guardiola‘s men to send us into next month’s final in Istanbul.
Walker, who played a key part in City’s clean sheet by nullifying the dangerous Vinicius Junior, paid special tribute to the team’s synergy after the victory.
“I’m glad it looked comfortable! It was tough,” he said. “The emotions sometimes take hold of you.
“I thought the lads dug in well. We controlled the ball really well especially in the first half. We got over the line and that’s the main thing.
“In this team, since I’ve been here, what I love is that everyone knows their roles and responsibilities.
“Of course we have Kevin [De Bruyne], Erling [Haaland] and Jack [Grealish], but there’s no real standout superstar who you can give the ball to and they do it themselves and it’s a goal.
“That’s what gets us across the line more often than not. We don’t rely on just one player.”

The Englishman, who will now compete in his and our second Champions League final, also reflected on his epic battle against Brazilian star Vinicius.
“You’ve got to have a little bit of arrogance, like the attackers do,” he said. “I say just go toe to toe with them. I believe in my pace, I feel I’m quicker than him.
“He’s fantastic. You have to use your own strengths. When players are running quickly, a little knock, not a foul, just a knock, then their balance goes. I made it as difficult as possible for him.”
The 32-year-old also reserved special praise for teammate Jack Grealish after the game.
Grealish put on a sparkling display and has now created 35 chances in this season’s Champions League campaign - the most on record by an English player in a single season.
“I tell him when he does well, and I tell him when he does bad,” said Walker.
“I play against him in training and he’s a nightmare. At this point in the season, he can’t do much better. He’s doing what he needs to for the team.

“If he can add a few more goals and chips in, ten a season is more than enough, plus the contribution you do in other areas of the pitch, then it’s enough.
“He’s the worst when he faces you up. He’s very intelligent and clever and that’s what he brings to the team.”
