Arsenal attacker Alex Oxlade-Chamberlain was delighted for Yaya Sanogo after this four goals in victory over Benfica.
Sanogo netted his first goals for the club against Benfica and the England international was delighted to see his team-mate impress in front of the Emirates crowd.
"I'm really happy for Yaya, he's been aiming to get a goal on the board for a little while so to get four is a statement," he said.
"I'm looking forward to seeing him this season and hopefully he can push on and help the squad."
