Arsenal returned to the Champions League in style as they started their first campaign in six years with an impressive win over PSV Eindhoven at Emirates Stadium.
The Gunners wrapped up victory in their opening Group B game with a scintillating first half display that saw them race into a 3-0 lead on a rain-soaked night in north London.
Bukayo Saka opened the scoring after eight minutes, pouncing on a rebound when PSV keeper Walter Benitez could only push Martin Odegaard's into the England winger's path.
Saka was involved again when Arsenal doubled their advantage 12 minutes later, laying the ball perfectly into Leandro Trossard's pass for a smooth low finish after Gabriel Jesus had broken clear.
Jesus was outstanding and thoroughly deserved to add Arsenal's third seven minutes before half-time with a rising drive that gave Benitez no chance.
Arsenal manager Mikel Arteta made a host of second-half changes with Sunday's derby at home to in-form Tottenham in mind, but his side still retained complete control, and Odegaard made it 4-0 with a powerful 20-yard strike with 20 minutes left.
