WHAT HAPPENED? Arsenal went into the game knowing they had to win to keep up the pressure on Manchester City following their win at Everton earlier in the afternoon, but after a tight first half against the Seagulls they conceded three times after the interval to fall to a painful 3-0 defeat. It was a loss that all but ended their title hopes with two matches remaining and speaking after the game a despondent Arteta could only apologise to supporters for what happened in the second half.
