Emile Smith Rowe’s early goal earned a determined Arsenal a Premier League victory at Stamford Bridge for the first time since 2011 as Chelsea missed out on the chance to secure a top four spot.
Kai Havertz blazed a one-on-one chance over the crossbar after pouncing on a loose touch from defender Pablo Mari, but Arsenal were not so wasteful when they were presented with an opportunity moments later.
Jorginho’s woeful back-pass almost ended up in the Chelsea net but was kept out by Kepa Arrizabalaga, before Pierre-Emerick Aubameyang squared to Smith Rowe to give Arsenal the lead.
Mason Mount was close to equalising but his goal-bound volley from eight yards was blocked by Rob Holding, before the England international had an effort save by Berndt Leno.
Christian Pulisic thought he had equalised after the break but his goal from a Chelsea corner was disallowed for offside. Chelsea failed to trouble the Arsenal goal until the dying stages when first Kurt Zouma and then Olivier Giroud hit the bar in stoppage time.
Here are five things we learned from Stamford Bridge.
Chelsea places at stake
In the grand scheme of their season, Wednesday’s London derby against Arsenal did not hold as much significance for Chelsea as Saturday’s FA Cup final against Leicester or the Champions League final against Manchester City at the end of the month.
But given the depth of Thomas Tuchel’s squad, as well as the German’s tendency to rotate, Chelsea’s players must know that every match is an opportunity to impress, and every under-par performance a potential blow to their hopes of starting either match.
With that in mind, there were a few in Blue whose chances of starting at Wembley might have taken a hit.
Havertz wasted a golden opportunity to open the scoring when he was presented with a clear run at goal but horribly miscued his shot, and struggled to get into the game before being replaced by Olivier Giroud. Billy Gilmour was brought off at half time, while his replacement Callum Hudson-Odoi was wasteful when he had opportunities to deliver.
Jorginho’s error also came a bad time with Matteo Kovacic nearing full fitness on his return from a thigh injury. As a result, it will not be a surprise to see Tuchel revert back to something closer to the line-up that beat City at the Etihad on Saturday when he comes to picking his side for Wembley.
