The Seagulls went unbeaten against Man City in the 2024-25 campaign, claiming a memorable 2-1 win at the Amex in November before they earned a spirited 2-2 draw on the road in March.
They came from behind twice at the Etihad and had chances to secure a win.
Hurzeler is looking forward to facing Guardiola again, but feels Albion are in a “different phase” compared to last season.
He told a press conference: “For sure (the win) highly ranks because I always emphasis Pep is the best, maybe the best in the world.
“It is always an honour to play against him and of course a joy to beat his teams.
“I think a different game on Sunday, a different team we will face and different phases.
“We are in a different stage, they are in a different stage and of course you can take a lot of positive things from these games but of course it is important to stay humble after these wins.
“It is not one game that makes a difference, it is the consistency that makes a difference.
“It will be a new challenge, a new opportunity for us to prove ourselves that we can challenge them and that is what we try to go for.”
