However, the Gunners now risk the ignominy of finishing the season seventh behind Burnley after a fifth consecutive away league defeat as they lost 2-1 at Newcastle on Sunday.
Guardiola's side arrived at Wembley on the back of three successive defeats, which saw them dumped out of the Champions League by Liverpool and miss the chance to seal the Premier League title by beating United.
"Our Time. Our City". Winning the title with five matches to go makes City the joint earliest champions in the Premier League era - matching the 2000-01 Manchester United team.
Guardiola hinted, via the Daily Mail, recently that City will need a big squad to compete with the likes of Manchester United and Liverpool again next season, adding that Silva may not be able to play every week because of his advancing years. Vincent Kompany did, with images showing the City captain celebrating at his in-laws' house where he was having dinner.

Peter Schmeichel was the league's best goalkeeper, Steve Bruce and Gary Pallister provided a rock-solid foundation in defence, while Roy Keane arrived from Nottingham Forest for a British record fee to form a formidable midfield partnership with Paul Ince.
COMPETE Many City have blown the rest of the Premier League out of the water this season
Instead of City hoping to clinch the title at home to Swansea next weekend, that game at Etihad Stadium will now be a party and a celebration of one of the Premier League's finest teams which could yet break a slew of records by the end of the season.
City could yet finish the season with the most points, goals and wins from a single Premier League campaign. My favourite title is still the first one - it was special. I have seen many teams win it as champions for the whole season, and it's the first case for us.
Few - including Guardiola - expected it to happen on Sunday. West Brom are a good team and don't deserve to be that low in the league.
For weeks it has been a case of when, rather than if, City win the title and it is nearly certain to happen within the next week.
City are 16 points clear of second placed United, who can only take a maximum of 15 points from their remaining five games.
"I don't know if I was the first or second or third but I congratulated them face to face when I had the chance", Mourinho said.
"Manchester City, we won it for you" chanted West Brom fans at full-time as United supporters began jeering in frustration at their side gift-wrapping the title for City. "City were the best team, sooner or later they would get the points, so no dramas when the best team wins the league", Mourinho said.
