Arsenal vs Brighton live updates: Hosts lose ground in Champions League race after Mwepu gives Brighton brilliant win

Arsenal lost ground in the race for Champions League places as they fell to a defeat against Brighton at home in the Premier League.

Brighton forward Leandro Trossard made Arsenal pay for a slow start by scoring a 28th-minute opener, firing home Enock Mwepu's cut-back. 

Gabriel Martinelli thought he had equalised just before half-time but was deemed just offside by VAR.

A goal at that point would have been terrific for Arsenal but instead, they continued to be troubled by Brighton.

The visitors got their second through Mwepu on the 67th minute following a brilliant move by debutant Moises Caicedo.

Martin Odegaard got Arsenal back into the with a long-range strike on the 89th minute and Arsenal knocked heavily on the door during the stoppage time, 

The Gunners have now lost three out of their last four games, and all of a sudden Tottenham are in the driving seat for fourth place.
