Arsenal returned to the top of the Premier League with a 3-0 win over Brighton.
The Gunners needed to win to keep pace in the title race after Manchester City dispatched Crystal Palace 4-2 in Saturday’s early kick-off.
Bukayo Saka gave them the lead in the first half from the penalty spot, after Gabriel Jesus was fouled in the area.
Although the hosts threatened a bit in the second half, Kai Havertz gave Arsenal breathing space, tapping in Jorginho’s low cross.
Leoandro Trossard then scored a breakaway goal to seal maximum points at the Amex Stadium.
Mikel Arteta’s men now have 71 points, one more than City and Liverpool, who travel to Manchester United tomorrow.
