Mikel Arteta refused to blame the pressure of the title race on Arsenal throwing away a 2-0 lead at West Ham as Man City tightened their grip on the main prize.
Arsenal were awarded a penalty at 2-1 up just after half-time for Michail Antonio's handball, only for Bukayo Saka to uncharacteristically put his effort wide. That proved even more costly when West Ham equalised two minutes later through Jarrod Bowen's smart finish.
When asked if the pressure was getting to his side, who have now dropped points in their last two games, Arteta said: "When I see a team playing with that flow [at the start of the game], that's not pressure. At 2-0 we were not under pressure. We just didn't do what the game required in that moment.
"We could not control what West Ham was proposing [after the first goal]. If you concede two or three goals away from home, it is very difficult to win football matches. We have to blame ourselves with how we played in our boxes."

It was the second game in a row that the Gunners had thrown away a 2-0 lead having drawn 2-2 with Liverpool last Sunday.
Arteta was asked if fatigue was to blame for their second half collapses.
He said: "Fatigue-wise? No. What we produced in the first and second half against Liverpool was similar and today we put a higher input in the second half that we did in the first half. We were slower in everything that we did. I don't think the team is fatigued or looked fatigued. The best way to do it is convince them how good they are and do what they have to do.
"We started extremely well again, dominated the game all over the pitch and scored two beautiful goals. After that we made a huge mistake, we stopped playing with the same purpose to score the third and the fourth one.
"It looked too easy. And on that moment, we gave them hope. Credit to West Ham, they took it. They did what they did really well, playing really direct with long throws and corners. We really struggled to get out of their game. If you don't defend the box the way we should, the two goals we conceded, then you have to do many other things much better.
"We need to have that ruthless mindset to go and kill a team. When a team is there for the taking, we have to kill the team. And when you don't do that in the Premier League, at some stage it's going to turn around.
"You have to fight and earn the right to play, but when we need it, you need to have more composure."
Odegaard: West Ham were dead, we did stupid things
Arsenal captain Martin Odegaard rued giving West Ham "hope when they were basically dead" - admitting his side did "stupid things" on the ball to let the hosts back in the game.
The Norwegian midfielder also admitted that the Gunners were guilty of repeating their mistakes from the previous week.
"A lot of the same things to last week," Odegaard told Sky Sports when asked how the game ran away from Arsenal.
"We played really well in the beginning, controlled everything and it went the way we wanted. Then we stopped with that.
"We gave them a little bit of the game they wanted. We gave them hope when they were basically dead. It's on us.
"We started to do a lot of stupid things with the ball and we let them play long balls, they got a lot of throw-ins and corners and we let them play on their qualities.
"We have to make sure this is not a problem. The most important thing is the next game."
Moyes: It was a big result
West Ham boss David Moyes said: "We tried to put Arsenal put under pressure, we were quicker and got up to people faster. We did a lot of things better today than we have before. We need to get back to it. It was a big result especially after being behind.
"At 2-0 down we didn't deserve to be as I didn't think Arsenal threatened much. They did look incredibly slick - I didn't think people were saying West Ham were bad, so for us to hang in and pressure them. And we got our moment with the penalty kick. It got us back in the game.
"Fine lines in football. It's so small. They get a penalty kick after half-time after we started well. We got good fortune with the missed penalty and then I fancied us to get a third one."
