Arsenal slipped to a shock 2-1 defeat against Brighton at the Emirates Stadium on Saturday as their hopes of finishing in the top four took a huge blow.
Brighton had failed to score in their last three matches but produced an impressive display to claim their first league win away from home since February.
Brighton took the lead after 28 minutes when Trossard was through on goal and produced a fine finish past Aaron Ramsdale.
The hosts thought they had equalised on the stroke of half-time but Gabriel Martinelli‘s goal was ruled out for offside after a lengthy VAR check.
Arsenal started the second-half brightly but found themselves 2-0 down after 67 minutes when Mwepu’s stunning half-volley flew into the bottom corner.
Odegaard grabbed a goal back for Arsenal in the 89th minute but they failed to complete the comeback and suffered a disappointing loss.
