Arsenal attacker Bukayo Saka admitted frustration after defeat to Manchester United in New Jersey.

United won 2-0 in Saturday's preseason friendly.

“It's obviously tough to take, whether it's a friendly or not against United," he said after the game. “We'll learn from it and you can't really give two goals away like that against a team like this because then it's really hard to come back. We just need to learn from it.

“Physically we want to get to a level that we were at last season and then go to another level and keep increasing that. Tactically we need to integrate everyone.

"We need to understand our game plan and how we play and keep progressing in each game so that when we come to the first game we're ready."
