Arsenal has been playing well since the start of this season. They have won 6 out of 7 matches. And today they won 3-0 against Brentford. We can't call Brentford's team weak. Because they have shown good performance in the last few matches. But if Arsenal wants to win the title, they must win against the likes of Manchester City and Tottenham. Winning the title is impossible if you are not able to beat strong teams. But I'm pretty sure now that Arsenal can qualify for the Champions League quite easily if they don't fall badly.
Brentford are currently still in good form actually and that is evident with them still in the middle of the table. but in this case it is clear Arsenal are on a different level so indeed they find it difficult to make changes to the result of this match.
The score was so striking and Arsenal returned to the top for a while.
