If Arsenal expected Brighton to roll over during their Sunday lunchtime kick-off at the Emirates, they were sadly mistaken.
While a rare Nacho Monreal goal gave the home side an early lead in the 16th-minute, the newly promoted side threatened to equalise during the opening 45 minutes.
But it was from one of Brighton’s attacks that Arsenal had a golden opportunity to double their lead before the break.
After a Brighton corner was cleared to the edge of the box, Solly March took far too many touches and was dispossessed.
What followed was an incredible Arsenal counter-attack and they soon had a four on two situation.
Alexis Sanchez, Aaron Ramsey, Hector Bellerin and Sead Kolasinac ran forward like the Red Arrows as Brighton were left exposed.
It ended with Kolasinac pulling the ball back to Ramsey - who saw his shot expertly saved by Matt Ryan.
Watch: Arsenal fail to score from counter-attack
Take a look:
While the speed of the break was impressive, football fans on Twitter couldn’t quite believe that they had failed to make it count.

To be fair, it was a tremendous save.
If the Gunners don’t lose to Brighton, it will be seven matches unbeaten in all competitions since their 4-0 loss to Liverpool back in August - only drawing once to Chelsea at Stamford Bridge.
Wenger on his 'different' team
And Wenger believes that this is a totally different Arsenal side to the one we saw at Anfield just a few weeks ago.
"We realised what we produced was not good enough," he said.
"But that game [against Liverpool] was a special day for us as well, it was just before the transfer window closed and before an international break and overall we stayed united and responded on the pitch.
"For me the weight of the transfer market was much heavier than the international break. It was a very difficult international break as well because you have two weeks to think about everything that happened.
"It feels like a different team [now]. You see the way we play football. You need to have a united group to do that. The opportunity we have is to go into this international break differently."
