Mikel Arteta admitted Arsenal only have themselves to blame after throwing away their second two-goal lead in a week to draw 2-2 at West Ham - in a major hit to their title credentials
The Premier League leaders got off to the perfect start as Gabriel Jesus and Martin Odegaard put the Gunners two up after 10 minutes with clinical first-time finishes - but just like last week at Anfield, Mikel Arteta's side could not hold on to their advantage
They conceded just before half-time when Said Benrahma struck from the penalty spot after Gabriel fouled Lucas Paqueta - before Arsenal were awarded a spot kick themselves 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
Antonio hit the bar for the Hammers in the final 10 minutes but Arteta's Arsenal will rue another two points dropped
"We could not control what West Ham was proposing [after the first goal]," Arteta said after the game
 "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 defended those two goals in our boxes
"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
"The result means Arsenal are four points above second-placed Manchester City having played a game more
 City's FA Cup semi-final next weekend means the Gunners can extend that gap to seven points if they beat Southampton on 
After that, Arsenal travel to the Etihad Stadium to take on Pep Guardiola's side in a crucial game for the title race
After seeing City score three in the first half against Leicester on Saturday Night Football, Arteta's Arsenal produced their own fast start with two goals in the opening 10 minutes
Gabriel headed Martinelli's cross wide early on but the opener would soon come
 Some intricate play from Odegaard, Partey, Saka and Ben White, who all combined to release the latter down the right byline, before he squared to Jesus for a simple tap-in
Four minutes later, it was two
 Another fast break saw Martinelli given the time to swish a superb ball to the unmarked Odegaard at the back post
 The Arsenal captain was left with the simple task of slamming home past Lukasz Fabianski
Arsenal accepted their two-goal advantage and sat on it - failing to create many other clear-cut chances, while enjoying over 75 per cent of the ball as the half went on
 At one point, West Ham fans showed their disgruntlement by booing their own side as they gave the ball away costly
But Arsenal invited the Hammers back into the contest as a slack Partey had his pocket pinched by Declan Rice, who feed Paqueta in the box quickly
Arsenal defender Gabriel came across and brought the Brazilian midfielder down - leaving referee David Coote no option but to point to the spot
Benrahma cooly slotted the penalty home as West Ham ended the half in the ascendancy
 Antonio saw a header from a Bowen free-kick tipped over by Aaron Ramsdale, before White deflected Tomas Soucek's header wide at a corner
Both sides showed some impetus going forwards in the opening minutes of the second half and it looked like Arsenal were taking a big step towards a third goal and the three points
Martinelli's shot hit Antonio high on the outstretched arm in the box and Coote was once again called to award a penalty
But Saka, who had scored all four of his Premier League penalties this season, missed the target of Fabianski's right-hand post - and the significance of that miss was amplified two minutes later
Thilo Kehrer lifted a long ball over Gabriel's head and Bowen was there to slam home past Ramsdale
A tense ending to the game saw both sides try to upgrade on the point they had
 Jesus came within inches of earning Arsenal's lead back as he failed to connect with Kieran Tierney's cross from a few yards out
Saka then tried to make amends for his penalty miss with a lung-bursting run on the break, but saw his shot falls gratefully into Fabianski's gloves
At the other end, Bowen searched for a winner on the break but his low shot was well-blocked by Tierney
Antonio produced the best chance of the final exchanges as he hit the bar from close range from Benrahma's cross
But the dropped two points - to go with the two dropped at Liverpool last week - could have major implications on Arsenal's title hunt
Arsenal manager Arteta hit back at claims that his side are feeling fatigued or feeling the pressure of a title race despite throwing away another commanding lead
"Fatigue-wise? No," he said in his post-match press conference
 "What we produced in the first and second half against Liverpool was similar and today we put a higher input in the second half than 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
Asked if his side are feeling the pressure of the title race, Arteta replied: "I would say 'yes' if I see a team playing with [gestures nothing]
 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
Meanwhile, David Moyes admits he expected his side to get a third goal after their equaliser - as he hailed a big result for the Hammers which moved them four points clear of the relegation zone
Moyes said: "We tried to put Arsenal 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 2-0 down
"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
"It's a fine line 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
"When Bukayo Saka put his penalty at West Ham wide of goal, it was the sign of how things can move away from the norm in a title race
Saka is normally so reliable from the spot
 His four previous spot kicks - against Manchester City, Liverpool, Manchester United and Chelsea - all went in
But the temperature is rising in the UK and so is the pressure in the title race
 At West Ham, it got to Saka, it got to this young Arsenal team
The last two Sundays are not how Arsenal have been this season
 Mikel Arteta's side have been consistent all term
 Free from injuries, fast starts, managing games, good responses to setbacks, fortunate with VAR calls, dramatic finishes
Fast starts have been there in their recent away games at Liverpool and West Ham
