Arsenal vs Chelsea: The Five Things We Learned As Chelsea Suffer Humiliation at the Emirates

• Frank Lampard's nightmarish rein as Chelsea manager continued unabated
• A spiritless display at the Emirates saw the Blues suffer an embarrassing loss at the hands of Arsenal
• The victory takes Arsenal to the top of the English Premier League temporarily, having played two more games than closest rivals Man City

Arsenal got their feint title hopes back on track with an emphatic win against Chelsea at the Emirates.

The Gunners snapped their three-game winless run with a statement win against the struggling Blues, helping the north London club usurp Manchester City at the summit of the league table, albeit temporarily.

A second-half strike from Noni Madueke did little to change the destiny of the game after a Martin Odegaard double and a goal from Gabriel Jesus handed the home side a deserved 3-1 win, returning to winning ways.

Sports Brief takes a look at the five key takeaways as Arsenal demolished their London rivals on Tuesday night.

Chelsea in complete shambles

Chelsea will look at themselves in the mirror and possibly regret the decision to appoint Frank Lampard as a caretaker manager following a run of six successive defeats.

The recent setback came at the hands of London rivals Arsenal, who unleashed their fury from their Man City defeat on the Blues, who were in absolute disarray and had virtually no response from Arsenal's non-stop, relentless attack.

For context, Lamparad's charges found themselves trailing three goals at halftime in a Premier League game London derby for the second time since going down by the same margin in 2016, per Opta Joe.

Arsenal still soft in defence

Should Arsenal fail to win the Premier League, which looks more likely, they would have to blame their soft-core defence. While their attack has been sublime, churning out goals on a regular the defence has struggled to do their part of the bargain - shutting the opponent out.

It was quite predictable Arsenal were going to capitalize on Chelsea's 'sorry state,' but another element in their game which was bound to rare its ugly head was their inability to keep clean sheets and allow opponents to fashion chances.

The Gunners had shipped in 10 goals in their last four outings, and, as expected, their clumsy backline came to haunt them, affording Noni Madueke the opportunity to score his debut goal for Chelsea.

Odegaard the magician

Martin Odegaard led by example as the Norwegian broke the game's deadlock, setting up the tone for the convincing and confidence-boosting victory.

The former Real Madrid prodigy, dubbed the "Wizard of Oz", weaved his magic with his wand cast in the mould of his left leg - scoring a brace, including a breathtaking curler, while taking his tally to 14 goals, per Transfermarkt.

Aside from his excellently taken goals, Odegaard was clever with his play - dropping deep into midfield to help Xhaka recycle possession while also linking up brilliantly with Trossard, Saka and later on, Gabriel Martinelli in the attack.

Aubameyang's horror show

Pierre-Emerick Aubameyang's return to the Emirates did not go as planned. The Gabonese forward he left the north London club acrimoniously was given a hostile welcome on his homecoming.

He was handed a rare start by manager Frank Lampard in a bid to give Chelsea a focal point in attack. However, it proved to be a difficult night for not only Aubameyang but the entire Blues setup, with Arsenal picking them apart.

He had a paltry nine touches in the 46 minutes he lasted on the field, with four of those coming from kickoff, highlighting his subpar performance.

Arsenal, Mydryk: no love lost

Fans of Arsenal, who had filled the Emirates to the rafters, gave Mykhailo Mudryk a hostile treat. The Ukrainian winger was forced to question his decision to snub north London for the Western part of the capital.

The former Shakhtar Donetsk was bound to join Arsenal in the winter transfer window but opted for their London rivals instead, which has since not gone down to plan owing to Chelsea's downward spiral in form.

Fans of the home side taunted Mudryk with the infamous song: “You should’ve signed for the Arsenal!” They also took turns to whistle at the 22-year-old, who made a cameo appearance in the London derby.
