Nacho Monreal says a quick start was key to Arsenal's victory over Manchester United.

The Gunners blew United away with three first-half goals.

Monreal told the Final Whistle: “We wanted to start stronger because in the last game, we played at home in the Champions League and we lost, so the memory wasn't good enough for us," Monreal added. “We knew that we were going to play against a strong team so we needed to start really strongly.

“I think we did - our first 15 minutes were amazing. We pressed high and I think we did everything amazingly.

“For this reason, after 20 minutes we were winning 3-0. We are really happy about our performance."
