New signing Gabriel Jesus kept up his fantastic preseason for Arsenal as the Gunners defeated London rivals Chelsea 4-0 in the Florida Cup final in Orlando, maintaining their perfect preseason record.
Dominant Arsenal, who also gave new £32 million acquisition Oleksandr Zinchenko his first start, were by far the better team as they played at Camping World Stadium in front of a record-breaking 63,811 spectators.
Trevoh Chalobah suffered a first-half injury for Chelsea, which saw Raheem Sterling make his debut and Kalidou Koulibaly limited to a late cameo.
After Chelsea lost possession of the ball, Jesus scored after just 15 minutes by dribbling the ball over Edouard Mendy.
Jesus, who has prospered since rejoining with Mikel Arteta in north London, scored his fourth goal in as many appearances for his new team.
Ten minutes before the break, the Gunners scored again, this time capitalizing on another gift of possession when Gabriel Martinelli found Martin Odegaard, whose shot nestled in the bottom corner.
On the cusp of halftime, Chelsea came close to regaining the lead, but Mason Mount’s powerful shot rattled the post and rebounded clear.
With 25 minutes left, Bukayo Saka scored from close range to extend Arsenal’s lead after Mendy made two excellent saves in quick succession to save both Martinelli and Xhaka.
Albert Sambi Lokonga, who was miraculously entirely unmarked to head in a right-wing cross from Cedric Soares, sealed the lopsided victory late in stoppage time.
In contrast to Chelsea, who won just once after losing to Charlotte FC on penalties in midweek and failed to keep a single clean sheet, Arsenal finished their US tour with three victories from as many games and nine goals scored.
On Friday, Chelsea will play their final preseason friendly against Udinese in Italy. The following weekend, Arsenal will play Sevilla in the Emirates Cup before opening the new season against Crystal Palace.
