Erik Lamela scored a sublime opener for Tottenham in the north London derby which left team-mate Sergio Reguilon in awe.
The Argentine started on the bench at the Emirates and was only introduced when Son Heung-min was forced off injured in the first-half.
But it didn't take him long to make his mark as he put the visitors ahead after 33 minutes.
Lamela's Rabona in a crowded penalty area arrowed into the bottom corner.
He reeled away in celebration and Reguilon's reaction was telling.
It wasn't the first time the Tottenham forward had pulled off the feat - doing so back in 2014 in a Europa League match vs Asteras Tripolis.
Jose Mourinho's side are looking to do the double over Arsenal this afternoon.
They won the reverse fixture 2-0 and have the top four in their sights.
Tottenham have won their last three - although wins at the Gunners have been few and far between over the years.
Mourinho poked fun at Arsenal before the game as he took aim at their league position.
"I look up, I don't look down. If Arsenal was seven points ahead of us, I would look to them," he said.
"But because we have seven points more than them, I don't look down.”
A win for Tottenham will move them to within three points of Chelsea in fourth, having played a game less than the Blues.
"We feel we're better than the position we have in the table and we want to improve our position so we need points for that," Mourinho said.
“It doesn't matter the opponent, doesn't matter if it is a London derby.
"It's a Premier League match, three points are there to fight for and that's what we're going to try to do."
