Arteta 'very disappointed' Arsenal didn't beat defensive Man City
Gabriel Martinelli's 93rd minute equaliser saved Arsenal's Premier League title bid from a damaging defeat to Manchester City.
The Gunners were heading to a second defeat in five Premier League games due to Erling Haaland's early strike on the counter-attack for City.
Martinelli came off the bench to score for the second time in a week to salvage a 1-1 draw, but both sides lost more ground to Premier League leaders Liverpool.
Arsenal went second, five points behind the champions, while City are eight points off the top in ninth.
"Very disappointed not to win," said Arsenal boss Mikel Arteta said. "I think we played better than last year when we beat them (5-1)."
Arteta's men had not conceded from open play in their first five Premier League and Champions League games this season, but were opened up on nine minutes by the scintillating form of arguably the world's best striker.
Haaland started the move deep inside his own half with a lay-off to Tijjani Reijnders and then sprinted upfield to receive the Dutch international's pass before coolly slotting beyond David Raya.
The Norwegian already has 13 goals for club and country in just eight games this season.
At the other end, City are reaping immediate dividends from the signing of giant Italian goalkeeper Gianluigi Donnarumma.
Noni Madueke's powerful near post strike was repelled by Donnarumma in what was Arsenal's best attempt in a flat first-half performance.
Mikel Arteta threw on the creative talents of Bukayo Saka and Eberechi Eze at the start of the second period.
Eze tested Donnarumma once more but the Gunners struggled to break down City's massed ranks of defence, with Guardiola even sacrificing Haaland and Phil Foden in the second half to bolster his back line.
However, that gamble backfired when Martinelli galloped onto Eze's ball over the top and looped a fantastic finish over Donnarumma.
"We don't try to be like this but when the opponent is better we defend deeper and counter-attack," said Guardiola.
