Arsenal scored twice from corners to comfortably beat Manchester United as Ruben Amorim suffered his first defeat in English football.
Defenders Jurrien Timber and William Saliba did the damage as Arsenal took advantage of Liverpool dropping points to trim their lead at the top of the Premier League table.
Arsenal sit third with 28 points, level on that mark with Chelsea and seven behind Arne Slot’s Reds.
The home side took the lead in the 54th minute when Declan Rice’s corner was headed in at the near post by full-back Timber.
The Gunners then almost doubled their lead when United’s Manuel Ugarte had to clear off the line after team-mate Joshua Zirkzee flicked on another Rice corner.
Saliba made sure of the win when Thomas Partey headed Bukayo Saka’s corner against the French defender’s back and the ball went past Andre Onana in the United goal.
