Maybe I wasn't surprised by Chelsea's draw against West Ham because I didn't fully believe in the performance of coach Graham Potter and his players, this kept Chelsea in 9th place in the standings. Meanwhile, the result that I think is very surprising is that Arsenal again failed to get a win after being held to a draw by Brentford at the Emirates Stadium. This result made Mikel Arteta have to keep working hard in the next match because he again failed to widen the distance from Manchester City in the standings.
Chelsea have not been good since Graham Potter became coach. The 1-1 result at home to West Ham United did not make many people disappointed because those who bet on the match had considered Chelsea's performance so far.
There has been no significant change to Chelsea even though the owner has spent a lot of money from his pocket to get good players.
Maybe that makes the Arsenal vs Brentford match unexpected for the draw. Usually the team coached by Arteta can score above 2 goals but in reality they cannot win at home.
But with the acquisition of a draw Arsenal can make the competition for the Premier League trophy tighter especially if Manchester City can win the match against Aston Villa.
