Gunners capitalise on Chelsea defensive errors to secure 4-2 victory

CHELSEA RATINGS: Edouard Mendy - 6: No chance with any of the goals as defence in front of him endured night to forget. Lacking confidence playing out from back after recent errors. AFP

Reece James - 6: Started in deeper, more central defensive role but Chelsea looked porous at back again. Pushed into preferred wider role as game wore on but couldn't provide team with cutting edge it needed after break. AFP

Andreas Christensen - 4: Terrible weak back-pass gifted Nketiah the opening goal and the Dane never looked comfortable. Hooked at half-time. Getty

Malang Sarr - 5: French defender couldn’t prevent Nketiah running through to score after Christensen blunder. Should have done a lot better dealing with Nketiah’s second, though. Booked for foul on Saka. Getty

Cesar Azpilicueta - 5: Lovely first-time finish to make it 2-2 for Chelsea captain’s first league goal of season. Gave away ludicrous late penalty after wrestling Saka to the ground and was booked for complaining. Then involved in confrontation with home fan after the final whistle. PA

N’Golo Kante - 6: Neat and tidy enough but Frenchman not his usual dominating self as Odegaard took control of midfield at key moments. EPA

Ruben Loftus-Cheek - 6: His well-timed challenge won back possession and led to Werner’s leveller. Ball watching as Smith Rowe ghosted in behind him for Arsenal's second and his influenced waned as match went on. AFP

Marcos Alonso - 5: Had shot in first few minutes deflected into side netting, then snatched at another opportunity and stunning long ball from Mount. Found Saka a handful, to say the least. Getty

Mason Mount 7: Had vicious swerving corner headed off line early on. Excellent ball into box to pick out Azpilicueta for his goal, an even better pass to find Alonso not long after that. AFP

Timo Werner - 6: German’s deflected strike from edge of box made it 1-1. Fired shot into side netting straight after half-time. Busy performance but, like his attacking teammates, strangely subdued in second half. Getty

Romelu Lukaku – 4: Striker, making his first league start for two months, drilled shot across face of goal and wide in 10th minute … but that was it for his attacking threat. Belgian looks shadow of the player many thought would propel Chelsea to title challenge. Reuters

SUBS: Thiago Silva – (On for Christensen 46’) 6: Veteran brought on to stabilise defence but was turned by Nketiah ahead of Arsenal’s third goal. Getty

Kai Havertz – (On for Lukaku 61’) 5: Brought on for hopelessly Lukaku, but then proved equally ineffective. AFP

Hakim Ziyech – (On for Alonso 81’) N/A. AFP

ARSENAL: Aaron Ramsdale - 6: Unconvincing on couple of early Chelsea corners and needed rescuing by Gabriel for one of them. Wrong-footed by deflection for Werner goal although the look on teammates' faces afterwards suggested they felt the goalkeeper should have stopped it. Getty

Ben White - 7: Sliding block early on sent Alonso shot into side netting. Arsenal felt he was fouled in run-up to Chelsea’s second but referee/VAR having none of it. Moved from central to right-back in fluid Gunners defensive line-up. EPA

Gabriel - 7: Headed corner off line after five minutes after Ramsdale flapped at cross then saw shot saved by Mendy at other end soon after. Booked after scuffle following late Gunners penalty. EPA

Rob Holding - 6: Very shaky from the off, gave ball away too easily and looked matter of time before one of his errors would lead to a Chelsea goal in first half. Much better after break. AP

Nuno Tavares - 6: Left-back always looking to push forward and fired shot across face of goal in first half. Showed lack of composure with one woeful shot wide from tight angle in second half. Getty

Granit Xhaka - 7: Nice dink over defence to set up chance for Gabriel but turned his back on Werner shot that then deflected off Swiss midfielder and past Ramsdale. Calm defending out from started move for second goal. Getty

Mohamed Elneny - 6: Rare start for Egyptian midfielder and relieved that Chelsea didn’t make more of his sloppy pass in own half after a couple of minutes, but solid enough show from then on. Getty

Bukayo Saka - 8: Skipped past with ease Alonso in first half to set up chance for Nketiah and did same just before break but no one in middle to take advantage. Dragged down by Azpilicueta for late penalty which the England attacker calmly finished himself. AFP

Martin Odegaard - 7: Gunners’ captain grew in stature as game went on, teed-up Smith Row for Gunners’ second and pulled strings at important moments. PA

Emile Smith Rowe - 8: Desperate for more game time and made his point with beautiful side-footed finish to make it 2-1. Wriggled his way past three defenders but fired just wide in manic first half. Getty

Eddie Nketiah - 8: Making only second start of season, attacker produced clinical finish after Christensen’s howler to open scoring. Hit two other chances wide in first half. Enjoyed a few lucky breaks from the Chelsea defence before stabbing home his second. AFP

Cedric Soares – (On for Smith Rowe 75’) 6: Looked lively after coming on but got caught in two minds after one run down right and failed to pick out a teammate. AFP

Arsenal secured a vital 4-2 victory over Chelsea at Stamford Bridge in what was a disastrous defensive performance by Thomas Tuchel's side.

In a breathless first half, Arsenal took the lead after Eddie Nketiah picked up an underhit back-pass by Andreas Christensen to run clear and finish confidently past Chelsea goalkeeper Edouard Mendy.

The Blues were level just four minutes later when German striker Timo Werner cut in from the left and fired a shot that took a massive deflection to wrong-foot Aaron Ramsdale in the Arsenal goal.

The visitors were back in front before the half-hour mark when Emile Smith Rowe finished off a swift Gunners counter-attack from inside their own penalty area.

But five minutes later, it was 2-2 after Chelsea captain Cesar Azpilicueta produced a fine first-time finish from a Mason Mount ball into the box.

The hapless Christensen was taken off at half time and replaced by Thiago Silva but Chelsea produced a laboured performance lacking in quality and urgency after the break.

Arsenal retook the lead when Nketiah capitalised on poor defending from Malang Sarr to toe poke home his second goal.

And Chelsea's misery was completed in injury-time when Azpilicueta pulled down Bukayo Saka in the box and the England winger picked himself up to score from the spot to complete a great night's work for Mikel Arteta's team.

Arsenal are fifth in the table, level on points with fourth-placed Tottenham Hotspur and the North London rivals play each other on May 12. Chelsea remain third, five points clear of Arsenal and Spurs, having played a game less.
