A seismic shift in north London punctuated a Premier League weekend filled to the brim of action at both ends of the table.
As Spurs were puncturing the last of Arsenal's ever-deflating belief that they can once more rise to consign their rivals another season in their shadow, Harry Redknapp, the man who contested more than his fair share of enthralling derbies north of the river was punching the air, issuing a call of defiance to the travelling QPR support as they gasped at a few bubbles of oxygen in their fight to avoid relegation suffocation on the south coast.
Both games pushed on the narrative in each key battle. Spurs now have control in the 4th place arms race - we've been here before - while QPR live to fight on another day.
Great games make great goals and there was no shortage of either this weekend - take a look at our selection of the top five goals below.
Wayne Rooney, Manchester United v Norwich
An unburdened Wayne Rooney in full-flight is something to behold, and when he wasn't teeing up a couple of glorious Shinji Kagawa goals he was topping the lot with a peach of his own.
In full gliding mode, Rooney dropped a shoulder, thrust a shot into the top corner and twisted the knife into a badly fading Norwich. Watch here.
Steven Pienaar, Everton v Reading
Beating Reading into a hasty retreat, Pienaar made his opponents pay with a show of speed and a turn of foot that once made him the object of Chelsea and Tottenham's affections.
The South African, handed the gift of space by his accommodating opponents, rendered Stuart Taylor's flailing grasp at thin air pointless with an arrowed shot on the fly.
Taylor, making his first Premier League appearance in five years, was welcomed back to the big time in some style. Watch here.
Shinji Kagawa, Manchester United v Norwich
A game for the purists who revel in subtlety, fluidity and skill, Shinja Kagawa - the one the fans had been sold as Eden Hazard's equal in the summer - finally arrived on Saturday.
His third of the game left Norwich dazzled and dazed by movement; Kagawa and his cohorts Welbeck and Rooney cut and weaved their way through the Canaries back line with a show of choreography and skill the Red Arrows would be envious of. Kagawa's first touch and chipped finish were sublime. Watch here.
Gareth Bale, Tottenham v Arsenal
Two blasts through the heart of Arsenal's drunk defence left them bleeding to death on a unfamiliar patch of north London grass. It came as no surprise that Gareth Bale was first in line to land the first of two fatal blows.
Scything on an angle, Gylfi Sigurdsson found Bale's scissor run that mocked Arsenal's attempts at a high flat line with ease. The Welshman demonstrated that his right foot is for balance purposes only as a he stroked an outside left-boot finish home past the hapless Wojciech Szczesny. Watch here.
Luis Suarez, Liverpool v Wigan
Rough, pugnacious, an irritant; but a coruscating talent who can grapple with a game and make it beg for submission - Luis Suarez shined as bright as ever against a punch-drunk Wigan.
Suarez - played in by a marauding Coutinho who exchanged neatly with Steven Gerrard before picking his pass his pass with a aplomb - left Ali Al-Habsi flat on his backside with a dummy or three, before sending the ball on its way into the back of the net. Watch here.
