Chelsea boss Antonio Conte believes the Gunners were lucky to win Chelsea.
Chelsea took an early lead through Eden Hazard before the Gunners leveled the scores due to an unfortunate own-goal that came off the head of Toni Rudiger.
Arsenal midfielder Granit Xhaka then scored the winner for Arsenal after Rudiger diverted a pass from Lacazette into the path of Xhaka.
“They were a bit lucky in these situations (the goals),” Conte told reporters.
“But we have to praise Arsenal.”
