City go into the tie having scored 27 goals in nine games since football restarted and Walker believes such firepower can make the difference in cup competitions.
The right-back says it is attacking prowess which decides knockout matches, and given our recent goal scoring exploits, he thinks we’re capable of beating any team.

“It’s a knockout game, it’s what both teams do in both boxes that makes the difference,” he said.
“I think the lads have proven that when we’re on fire and things go our way, we can go and score three, four and five goals and maybe even seven or eight.
“Hopefully, we can do that against Arsenal. We know Mikel knows how we play. It will be difficult to break them down and they’ve got good players in good areas.
“But I think on our day we can beat anyone.”
Walker also thinks the depth of talent in City’s squad gives us an advantage in knockout games.
The 30-year-old has first-hand experience of how this team can exhaust you both physically and mentally and that is something he feels our substitutes can exploit if Saturday’s clash proves to be a cagey cup affair.
“I’ve played on the receiving end of City when I was at Tottenham and you feel you’re having a good day and your defence is playing well and then all of a sudden one goes in and you think you’re still in the game,” he explained.
“With this squad, it’s not just the players who are starting, but coming off the bench. They can make the difference if you’ve run for 70 minutes and you’re defending balls and onslaughts of attacks.
“If different players are coming on with fresher legs and more energy, it’s good ammunition to have in your back pocket that we’ve got in abundance.
“It’s great for us to have. It’s not just about the 11 that start, it’s about those on the bench and whoever the manager brings on.”
