LONDON — Manchester City were confirmed as Premier League champions for the fifth time in six seasons on Saturday without even having to kick a ball after second-placed Arsenal’s challenge ended in defeat away at Nottingham Forest.

Arsenal, who enjoyed an eight-point lead over Manchester City as recently as mid-March, needed at least a point to stay mathematically in the hunt, but went down 1-0.

City, who host Chelsea on Sunday after which they will be presented with the trophy, have 85 points with three games to play, while Arsenal are on 81 with one game left.

It is City’s seventh Premier League title since they were bought by Abu Dhabi’s Sheikh Mansour bin Zayed Al Nahyan in 2008 and they are now just two wins away from completing a treble only previously achieve by Manchester United in 1999.

City face Manchester United in the FA Cup final on June 3 and a week later take on Inter Milan in the Champions League final — starting big favorites in both games.

Manager Pep Guardiola has now won a total of 12 trophies since being hired by City in 2016.

While Arsenal have threatened to knock City off their perch this season, it all proved an illusion in the end as Mr. Guardiola’s side again proved relentless in the run-in.

Since losing to Tottenham Hotspur on Feb. 5 they have taken 40 points from the next 42 on offer and have 11 successive league games, beating Arsenal comprehensively home and away.

If City win their last three games they will reach 94 points, not as many as the totals they achieved in 2017-18 and 2018-19, Mr. Guardiola’s first two league titles.

City have now joined an elite group of clubs to win three successive English top-flight titles, with Huddersfield Town, Arsenal, Liverpool and Manchester United the only others.

The club’s website featured animated tickertape flittering down the screen with a live video showing an enormous banner being unfurled down the side of the Etihad Stadium stating “Three in a Row”. — Reuters
