Arsenal have been crowned Premier League champions after Bournemouth ended Manchester City’s challenge and denied Pep Guardiola the chance of a final title as Manchester City manager.Guardiola, who The Athletic and other organisations reported on Monday is to leave the club at the end of the season, said the news had “zero” effect on his side’s preparations when he spoke briefly before tonight’s game to Sky Sports, who did not ask if he was departing.City had to win to take the race to the final day and in a lively start, their Bournemouth old boy Antoine Semenyo finished a fine move only to be ruled offside. The flag was also up when Evanilson met a low cross seven yards out for the hosts but managed to knock it over the bar.Bournemouth took the lead on 39 minutes when teenager Eli Junior Kroupi curled a shot past a rooted Gianluigi Donnarumma from just inside the box. City responded strongly after the break and Djordje Petrovic saved Nico O’Reilly’s shot from close range. David Brooks almost added a second for Bournemouth when he hit a post and though Erling Haaland crashed in a stoppage-time equaliser, the 1-1 draw was not enough.That result means Arsenal are champions for the first time in 22 years.Bournemouth are now three points behind fifth-placed Liverpool and a guaranteed place in next season’s Champions League heading into the final day of the season on Sunday, where they visit Nottingham Forest while Brentford go to Anfield.The Athletic’s Sam Lee and Thom Harris break down the key moments.Why did City’s title challenge fail?This always looked like a tough game, even before Monday’s big news broke. Bournemouth were on a long unbeaten run dating back to early January that may have contained a lot of draws, but another one would have been enough for them to clinch European football, and ruin City’s title hopes once and for all.City needed nothing but a win, but came here looking flat even after they won the FA Cup final on Saturday. Bournemouth, by contrast, had had 10 days to prepare. City would have had a decent amount of hope that they could win the title on the final day if they had got the job done here, but that was always a big if.Ultimately, their title challenge fell apart not just because of this result, but due to the flaws in the team throughout the season that cost them points in too many games.City fans may argue about which match was the most disappointing — was it the back-to-back home draws against Chelsea and Brighton at the start of January when they’d been leading 1-0 in both? The 2-2 draw at home to Nottingham Forest in March, where they were in front twice? The 2-2 at Tottenham, having been two up at half-time? The 1-1 at West Ham, in which they also scored first? The 3-3 at Everton?
