There's no underestimating the Arsenal team at the moment. In the past matches we have seen that Arsenal have won most of the matches by big margins. Arsenal players have the ability to break down any team's defence. Arsenal's attacking players are also in very good form right now.
Lots of people are under estimating Arsenal, honestly if I will be saying the truth, am also underestimating Arsenal, because of how they do perform every season. Arsenal have been winning their matches lately with wide goal difference, that’s just because they we’re playing against week teams, most of the clubs they scored with a wide goal margin were average clubs, I will be calling Brentford a average club also but we saw how they played against Arsenal in their last last match, if not that Arsenal were lucky, the match would have ended as a draw, which that was what Brentford wanted in the match.
