For the first 15 minutes Brentford looked solid but goals will come in this game, it's pretty fast paced and both team may score. Nunez at the front while Salah is in the bench. Brentford is looking for a goal with Toney and Maupay.
Arsenal has an easier opponent. I don't think that will be hard for them to score. Burnley is one of the worst teams in PL and they haven't won a game for a long time. Arsenal scored a lot lately, this one should be the similar. Saka, Trossard, Rice, Martinelli all in form players.
