Arsenal boss Mikel Arteta, speaking to BBC Sport: "The game had moments. We started without the control and dominance we wanted but after that we got the rhythm and had situations to score.
"We started the second half brilliantly. We scored the goal and then we controlled the game but after that the game became chaotic.
"The moment you start to give away one or two free-kicks, the ball goes into the channels in can go out for a throw and then it is a nightmare. They can throw the ball from anywhere on the pitch. You get into that game and it is very difficult to get out.
"They are one of the best historically in the league [from set-pieces] and they have developed this year with the long throw. It is a real threat and difficult to defend.
"We were giving free-kicks away you cannot do. We should have had more composure to play through them.
"We wanted to win so we feel like we dropped two points. They are very difficult. We keep going."
Declan Rice, speaking to BBC Sport: "The game was split into different halves. It was their first 20 minutes, we ended the first half strong, we started the second half amazingly well and they ended the half better than us. We suffocated a lot after the goal.
"In this journey you are never going to be at the level for 70 games of the season but you have to be at the best you can. The small details, the basics, like I say this is a rollercoaster of a season. You can't be naïve to think this is going to be easy. We are playing against the best teams week in, week out. We have to keep pushing and believing in ourselves, controlling the controllable.
"We have to block out the outside noise. We have done that really well. People are going to talk up the title race and Arsenal but we have a really calm group. I'm not naïve to think Brentford are a pushover. They are one of the best teams in the league and their recent form shows that. It's a point gained in our journey but we wanted to win the game."
