Arsenal 1-2 Man Utd: Youngsters can do better - Louis van Gaal
Manchester United manager Louis van Gaal says his young defence "can do better" despite his side's 2-1 win at Arsenal.
An own goal from Kieran Gibbs and a Wayne Rooney strike gave United the victory, with the hosts claiming a late consolation through Olivier Giroud.
This was van Gaal's first away Premier League win as Manchester United boss.
