Following their loss at Wembley on Saturday afternoon- courtesy of a Harry Kane header- the Gunners find themselves in sixth place, six points adrift from the top four.
"The top four is hard now as this is a game we could not afford to lose, but it's too early (to focus on winning the Europa League)".
"He's an authentic legend of this club", City manager Pep Guardiola said of the striker who clinched City's Premier League title in 2012 with nearly the last kick of the season.
Although Kane was named Man of the Match, it was the display of Jan Vertonghen that got Spurs supporters talking on Twitter.
"I don't think they lack hunger to defend", he declared.
Why on Earth did Arsenal try to park the bus against Tottenham?
Arsenal is in sixth place, six points behind fourth-place Liverpool , which does not play until Sunday. The priority has to be to be in the Champions League through the Premier League .
"I think they have done an incredible job, they are the team that you can praise the most in the Premier League, what (chairman) Daniel Levy has done, the way they have organised the club", said the Daily Telegraph's football writer.
And it was only the defiance of Cech that kept a rampant Spurs at bay in the second half, producing a collection of outstanding saves to somehow keep Arsenal in contention as Pochettino's side threatened to run riot.
His last-gasp penalty against Liverpool last weekend saw him join the Premier League "100 club" at just 24 years of age, and there is growing expectation now that Kane will threaten Alan Shearer's record tally of 260 top flight goals before he hangs up his boots.
Totttenham were good value for the win at the national stadium, but only claimed all three Premier League points thanks to a Harry Kane header in the 49th minute. For the second consecutive away derby, Arsenal failed to score against Tottenham - something that hasn't happened since 1975.
7 - Harry Kane has seven goals in seven Premier League north London derby games - only Emmanuel Adebayor has scored more (8). "On the final ball, we missed something". "We contained them to very little", Wenger said in his post match interview.
"Once they scored you could see we were wobbling for a while and they could have scored one or two more, but in the last 10 minutes we should have come back to 1-1".
