The Arsenal team is now in form. Now they can play well against any team. But I don't think the Brighton team is weak. Their performance so far this season is better than Arsenal's. Brighton have lost just one match so far. Interestingly, Brighton have conceded just five goals in six matches. Arsenal, on the other hand, have conceded 10 goals in 6 matches. It is easy to understand that Brighton's defense is strong enough. However, this match is most likely to be a draw.
Maybe it is a draw.However keep in mind these last couple of years Brighton has mostly won against Arsenal when they were playing at home.It is high likely they are going to win again against Arsenal tonight and the win against Tottenham doesn't prove anything cause they are a weak team this year.The Premier League is always full of surprise results so we can expect any result.
