Hurzeler speaking to BBC Radio 5 Live: “I repeated myself the last two, three four weeks when I said that we should have won this game or that game, and again today, that is what frustrates us.
“We are not able to play consistently, to press consistently, we cannot go for 90 minutes with the intensity that we showed in the second half.
“We are not clear enough with goalscoring chances. We have to work hard on ourselves and look in the mirror and see that we are responsible for the result.
“Arsenal did not create that many goalscoring chances. The only shot on goal was their goal, therefore we also see the positives. But we have to work on consistency.
On the penalty decision: “Clear penalty.”
On Joao Pedro: “He had a tough period but we know his quality. He is one of our leaders, he is in the leadership group. He was our captain today when Lewis [Dunk] was injured and he showed his quality.
“He got the goal but more importantly his performance was about how he led this young team. He was a role model, his work against the ball, counter pressing and sprinting back.”
On the coming games: “We want to be fitter and sharper, so we have to be physically and mentally on a different level and we need to work hard to get there. We as staff have to be ready to push the players so they are as ready as they can be. “
“It was clearly headed by Saliba,” said presenter Gary Lineker on MOTD. “Never ever have we seen a penalty given for head clashes.”
Danny Murphy: “They both head the ball before they clash. They are genuinely going for it. It’s a coming together.”
Jamie Redknapp on Sky Sports: “When you think about Gabriel and Saliba you think about calmness, but there was chaos in Arsenal’s defending there,.
“The defending was chaotic. Is it a penalty? Absolutely. You can see the contact. He heads him and he goes down; you can’t afford to do that in the box.
“We have seen a lot worse penalties than that one. They were rash in their defending. I can see why people say it’s soft, but he is hit on the head and goes down. It’s a foul. Arteta is entitled to his opinion, but they didn’t play well. That is the fact.”
Steve Sidwell: “It was a genuine attempt to get the ball, but Pedro gets there first. I think it’s a penalty. A clear penalty for me.”
Matt Upson: “A clash of heads. It’s an interesting one. How often do you see a penalty given away for an accidental headbutt?”
Brighton defender Jan Paul van Hecke, speaking to Sky Sports: “I think we did quite well. We shouldn’t have conceded the first goal. That shouldn’t happen to us, but you can see a lot of character in the boys. We need to be more consistent.
“We have a really young team. The average age of our team is 23. It’s tough sometimes, but our guys fight for everything. Maybe you need a bit more experience to manage the game.
“In some parts we are really good. Consistency is an important thing for us to get back where we need to be.”
Brighton goalscorer Joao Pedro, speaking to Sky Sports: “We started the game well. We could have won but got a point. We need to look forward.
“We conceded in the first half but knew we could win this game. We tried to score at the beginning of the second half. We wanted to win.”
On the penalty: “I tried to control the ball and then [Saliba] hit me. It’s good that I scored. I always try to be positive with goals and assists. I like the feeling [of scoring] and hopefully I’ll score more.”
Brighton defender Jan Paul van Hecke speaking to BBC Match of the Day: “I am not to be honest [thinking of it like a win]. We now have a streak of eight games without a win. Of course it is a good point against one of the best teams in the league but we also need to win games. The first half was not good enough from us and we concede a goal that can’t really happen in my opinion. You saw a different team in the second half.
“All season you have seen parts where we are really strong and good where we can be the best teams in the league then halves or parts in the game we are not and we belong to the worst in the league. Consistency is the word and we need to be better in the future.
“The intensity we played with. We really went toe-to-toe with them and then you see we are very strong. When we score we should maybe score another one. In the end it is a good result.”
On Brighton’s penalty: “I have not seen it back. It is hard to judge. I think there was small contact. Last week against [Aston] Villa there was small contact and it went against us.”
On Joao Pedro: “I think he was brilliant today. Not only for the penalty but for his work rate. We need that every game from him because he is one of our best players and he can lead us.”
Arsenal defender Riccardo Calafiori, speaking to Sky Sports: “I think we felt we could have done a bit better to manage the game and [manage] the goal we scored in the first half. We should have scored another one.
“I don’t know why we made so many stupid mistakes, but the good thing is that we play again in three days [against Newcastle in the Carabao Cup]. Maybe we were too low and gave the opponents too many balls.
“It’s not a big loss. We have to keep going now and win the next game.
“It’s not the moment to think too much about the title. We need to focus on ourselves.”
Arsenal defender Riccardo Calafiori, speaking to BBC Match of the Day: “You can see from my expression that I am frustrated and disappointed. We could have done better for sure.
“The good thing is that we have another game in two or three days and we are already thinking about that.
“The first 25 minutes was how Arsenal should play and then we could not dominate the game. From tomorrow we will forget about this game and think about the next one. The season is so long.”
