Arsenal will fail to win that game, and at least that's what I implied in my mind about Arsenal's next match.
I could be very wrong about this, but Brentford are a tough team to beat so far due to their success in keeping form. The most likely result is a draw, but whatever it is is still hard to predict because Arsenal certainly won't give up too easily to get back on their feet after the defeat to Everton.
Brentford is a pretty good team and have been in a very good form but, Brentford vs Arsenal, I don't think Brentford makes that match. Arteta might have lost his last game against Everton but, I don't think that would be enough to put them off mentally from there winning ways. Good enough Manchester City wasn't able to take advantage of Arsenal's lost game to close in on the point gap and Arteta is more than ever determined to keep it that way.
You can tell how furious he was after they lost that game against Everton and that's what his got to work on when they face Brentford.
Brentford is indeed one of the clubs that continues to show fairly good consistency at the moment. even Brentford has only 4 defeats from 21 matches. But Arsenal's strength is much better this season. Arsenal also only have 4 defeats from 20 matches. And of course Arsenal have more wins. I think Arsenal will win the game against Brentford. perhaps the worst result is a draw. but I will believe in Arsenal's advantage.
