Arsenal beat Manchester United 2-0 in the Premier League on Wednesday at the Emirates Stadium to secure their first win under new manager Mikel Arteta.
The Gunners enjoyed a dominant first-half performance and took the lead after just eight minutes when Nicolas Pepe side-footed Sead Kolasinac's cross past goalkeeper David De Gea.
Arsenal added a deserved second three minutes before half-time. De Gea could only parry a flick on by Alexandre Lacazette at the near post, allowing Sokratis to smash the ball home from close range.
Manchester United improved after the break but could not find a way back into the match and slip to their sixth Premier League defeat of the season.
