So you can imagine the glee on Arsenal faces last night when Aaron Ramsey and Alexandre Lacazette fired Unai Emery’s side two points clear of Tottenham in the Premier League table.
If there was power shift, it was certainly short-lived.
Of course, with seven games still left to play – Spurs could still make it a third consecutive season of finishing above their biggest rivals of all.
Pochettino will back his side to accomplish that feat, too.
But for now, whatever gap Tottenham believed they’d built over the Gunners has been wiped out in less than a season by Emery.
Winning their first game at their new £1billion stadium against Crystal Palace on Wednesday night takes on even more significance for Tottenham now.
Finishing above Tottenham has more profound consequences for Arsenal than just bragging rights, of course.
Aubameyang forced Dubravka into a good save with a fierce drive in the 75th minute as the Gunners made hard work of putting the encounter to bed.
You could sense the anxiety grow at the Emirates as every minute passed. Winning meant so much last night. More than usual.
And gradually, Newcastle began to threaten; substitute Ki Sung-Yeung fired over during a rare venture forward as Arsenal’s nerves continued to jangle.
But Lacazette finally sealed all three points, nipping in front of Jamal Lascelles to loft Aubameyang’s header over Dubravka in the 83rd minute.
Supporters, on a night their team did the business, were intent on letting Tottenham know about it.
