Actually Chelsea really tried on that there match against Arsenal because considering Arsenal performance and how they played against Manchester city I was thinking they will win Chelsea with 3 goals, but on the contrary Chelsea performance proofs very impressive to have managed to score Arsenal first and second, I was actually surprised by there performance.
So when we talk about defense, actually Chelsea defense was more stronger than Arsenal defense on that match but however Arsenal manages to equalise and draw the game.
Chelsea really have to get up from now on before they fall further behind their rivals, because this draw also started to prevent Arsenal from immediately becoming top of the standings before Tottenham won over Fulham. And in the next match, it is also highly hoped that Chelsea can win at home when they host Brentford because this is part of their efforts to improve their position for the better before the first round of this season ends.
