City and Villa, separated by a single point in the league table, are part of a congested race for a top-four finish, with Newcastle United, Chelsea, and Nottingham Forest also in contention. The stakes have intensified as the season approaches its conclusion, and Guardiola made clear the significance of Tuesday's fixture.
"We need our people - hopefully they can help us from the first minute," Guardiola said in a press conference. "Do not wait, because sometimes we are sloppy, sometimes we are not playing well, but this is the moment we need them.
"We need them desperately - to support us, to make noise, and to be present all the time. This is a final. Absolutely, it is a final for us. And after Aston Villa, the game against Wolves will also be a final. Then it will be the same against Southampton, because every point, every match, counts."
Aston Villa arrive in Manchester in strong form, having responded to their Champions League exit at the hands of Paris Saint-Germain with an emphatic 4-1 victory over Newcastle United. Under the guidance of Unai Emery, Villa have won 11 of their last 13 matches across all competitions and have emerged as serious contenders for European qualification.
Guardiola spoke with considerable respect for Villa's resurgence and Emery's tactical nous, acknowledging the challenge his side will face.
"They are very much in the race for the Champions League. I watched both matches they played against Paris Saint-Germain, managed by my friend Luis Enrique - and I must say, I was extremely impressed," Guardiola commented.
"They can operate effectively in a low defensive block, but when they decide to push forward, they are formidable. The pace they possess, their organisation, their proficiency from set-pieces - they are a complete side. This match is a final."
While Aston Villa have not secured a league victory at the Etihad since 2007, form and recent history suggest they are more than capable of upsetting that trend. For Manchester City, the pressure is immense, and Guardiola has made it abundantly clear that the club's supporters have a crucial role to play in what could prove a decisive stretch in the campaign.
