Arsene Wenger says Arsenal's performance in their 3-0 thumping of Chelsea at the Emirates was one of the best since he became the Gunners' manager 20 years ago.
Three first half goals from Alexis Sanchez, Theo Walcott and Mesut Ozil secured Arsenal's first win against Chelsea since their 5-3 win in 2011 at Stamford Bridge.
Reacting to the win, Wenger however stated that Arsenal need to improve.
"There is room for improvement… (But) it's one of the best performances in recent years," Wenger told reporters.
"It's one of those moments in your life as a manager where you think today is one of the best in you career."
The French tactician went on to reserve special praise for Theo Walcott.
"Theo Walcott is ready to fight, he's committed, and a Theo Walcott with the crowd behind him is a completely different player."
