The story of Arsenal’s summer was ending up with fewer attackers than they started, but in this comeback win against Chelsea, they showed that they still have enough to perform in the biggest games.Morgan Rogers was one player they went for and missed out on, and it was the former Aston Villa forward who opened the scoring for Chelsea within two minutes.But then former Chelsea forward Kai Havertz, who was excellent throughout and received a standing ovation when substituted, equalised as Emi Martinez struggled to get down in time. Pedro Neto hit the post before the break.The second half was much the same in terms of entertainment as Xabi Alonso’s side continued to threaten, especially on the break, but it was Martin Odegaard who put Arsenal in front with a goal similar to the one they scored against Manchester City in the Community Shield. David Raya then made a great late save from Estevao.Considering the control Arteta and Arsenal desired in games last season as they won the Premier League, this was very open and, with it, entertaining. There were also moments of controversy, as Gabriel seemed to kick out at Martinez and Declan Rice tripped Rogers. But for Chelsea, there were positives in the way they threatened on the break and had chances throughout.Art de Roché, Liam Twomey, Jack Lang and Conor O’Neill break down the action.How good was this game?It has been, all told, a relatively low-key start to the Premier League season. For all the movement in the transfer market, many teams have begun the season looking slightly adrift, a little rudderless. The contrast with Arsenal, a picture of stability, has dampened hopes of anything even remotely resembling a title race.Only time will tell whether we get one. This, though, was a match to fire the imagination — a rolling, shape-shifting battle that will take some living up to in the months ahead.Arsenal were good value for their win, playing with craft and bite. But there were, in Chelsea’s display, signs that the champions may not have things all their own way. In the first half especially, the away team tugged Arsenal around, and might easily have built upon that early Rogers goal.Their efforts challenged Arsenal and, eventually, made their comeback feel all the more significant. This was no sterile victory; it was emotional, stirring, a victory of the spirit. Both sides emerge from the game with reason for hope. So, importantly, do the neutrals.(Stuart MacFarlane/Arsenal FC via Getty Images)Jack LangHavertz brilliance: goal, a dummy, leading the lineWe live in a data-driven era where every on-ball action is codified, weighted and measured. But Havertz’s clever dummy for Odegaard’s goal was a reminder that assists and chances cannot capture every flash of creative brilliance.After Christos Tzolis cut inside off the left, Havertz drifted into the central area in front of the box, demanding the ball with a raised arm. Tzolis obliged, playing it into him, but the gesture proved a classic case of misdirection.Havertz extended a foot as if to collect the ball, only to withdraw it just as quickly, allowing it to roll through to Martin Odegaard in the centre of the penalty area.Odegaard duly applied the calm finish, a goal that will go down as a Tzolis assist. The Greek winger will take the boost to his creative numbers, but he will know it was Havertz’s uncredited contribution that proved decisive.It capped a brilliant overall performance by Havertz. He scored his fourth goal in seven appearances against his former club, who struggled to contain that marauding creativity that makes the German so hard to stop when in full flow.Conor O’NeillHow did Rogers and Chelsea’s front three look?Arsenal opted not to match Chelsea’s £117million offer for Rogers in July, so it felt like the football gods were having fun by seeing to it that the most expensive British footballer ever’s volley nestled in the back of David Raya’s net with 1:17 on the clock at the Emirates Stadium.To have any hope of competing against the Premier League champions, Chelsea’s vaunted front three had to demonstrate that a Gunners defence which has carried its aura of invincibility into the opening weeks of this new season could be made to bleed.It was no shock that Rogers, rather than Cole Palmer or Joao Pedro, was the man to do it. Of the three, he is the natural risk-taker, the man who tries things that others won’t — like volleying a dropping ball from outside the box, for example — in his quest to make something happen.(Adrian Dennis / AFP via Getty Images)At times, that risk-taking instinct can make Rogers lose possession in bad areas, creating more defensive work for his team-mates. But he has already given Chelsea’s attack under Alonso a new, more direct dimension to anything this team had last season, and he is already dovetailing with Palmer and Joao Pedro beautifully.On the half-hour mark, he latched onto a perfectly measured long kick from Emi Martinez, exchanged passes with Joao Pedro and then shifted the ball inside Ezri Konsa and whipped a shot just wide of David Raya’s far post.Konsa got the better of his former Villa team-mate with a thunderous sliding tackle in the second half, but Rogers always forces opposition defences to react. That makes him valuable even when his best-laid plans in the final third aren’t quite coming off.Liam TwomeyArsenal fluid and rotating in attack?Arsenal had no choice but to go all out after conceding on 77 seconds and seemed better for it.Instantly, there was a crispness and intent to their play, which manifested in Bukayo Saka, Odegaard and Ben White making their right flank look just as threatening as it did on the opening day win over Coventry.Unlike the previous season, however, Arsenal were not dependent on that right wing. Tzolis took the more direct route as his runs in behind gave Arsenal a dual threat to keep the entire Chelsea back line honest.It was Arsenal’s constant positional rotations and short passing on the right that made the difference, however. Havertz pulling to the right, combined with the snappier passing of Rice, is what brought their equaliser.Tzolis and Odegaard’s developing on-pitch relationship is impressive too. Their combination to put Arsenal ahead was almost a carbon copy of the Arsenal captain’s goal against Manchester City in the Community Shield last month.For the Greek international to be so consistent with repeat actions like that tempting pass should be a massive help to Arsenal throughout the season.The endless movement of red and white shirts also helped with Havertz’s role in Arsenal’s second goal.Art de RochéHow can Chelsea sort midfield issues?It is to Romeo Lavia and Reece James’ great credit that Chelsea supporters did not spend most of this game pining for Moises Caicedo, or even Lamine Camara.Chelsea were in survival mode for long spells of the first half after Rogers put them ahead, but it might have been Lavia’s best half of football defensively since he joined the club. He was jumping into the press high up the pitch to force Arsenal mistakes, sniffing out danger in his defensive third and screening off passing angles effectively.James, meanwhile, largely lived up to Alonso’s bold assessment of his potential as a midfielder, bringing class and composure to Chelsea’s spells of possession.But the absence of Caicedo and additional quality options was felt more keenly in the second half, when Odegaard managed to run off James to put Arsenal in front.Lavia’s tank generally runs empty around the hour mark, and it was telling that Alonso turned to Malo Gusto, another natural full-back, to replace him rather than Valentin Barco.Gusto brought good energy to Chelsea’s final push but he does not have the on-ball quality to pick apart Arsenal’s low-block defence, though he did help their transition defence.Even if Caicedo is back sooner rather than later and James can be as good a midfielder as Alonso believes, Chelsea’s manager needs a bit more against opponents of this calibre.Liam TwomeyBattle of the set-piece coaches
