For many years the north London derby held a reputation as the bragging rights battle that always delivered a tussle of fearsome competitiveness.
Yet the times, they are a-changing.
Between 2010 and their final duel of the 2012/13 campaign both sides found the net in eight consecutive clashes.
Bar the two collisions between our adversaries in 2009, 16 of the most recent 18 north London derbies prior to the 2013/14 campaign saw both teams on target.
Investing in over 2.5 goals was virtually a given, with wagers copping in all but two of those fixtures.
But something’s afoot in the north-east of the nation’s capital.
Since the start of last season Arsenal have met Tottenham on three occasions, winning to nil each time.
They’re 39/20 to make it four in a row when Spurs arrive at the Emirates at teatime on Saturday, but what is behind the change in character of this previously tumultuous fixture?
While the likes of Carl Jenkinson, Nacho Monreal and Thomas Vermaelen all featured in Tottenham’s 2-1 win over the Gunners in March 2013, various members of that rogues’ gallery featured in two of last season’s three shutout successes.
Indeed any suggestion that Arsene Wenger’s troops’ defensive improvement is behind the changing character of the derby is wide of the mark.
After all Arsenal conceded less league goals in 2012/13, when the aggregate of their two meetings with the Lilywhites was 6-4, than last term.
Nor is the Gunners’ dominance down to an increased monopolisation of possession in midfield, with Tottenham claiming 59 per cent custody in the most recent meeting.
As such the blame for last season’s unusually sterile north London derbies can be laid squarely at the feet of Mauricio Pochettino’s men.
It’s no coincidence that the departure of Gareth Bale was the harbinger for the White Hart Lane club’s 2013/14 triple bagel.
Tottenham’s inability to replace the marauding Welshman highlights an on-going downgrade in their attacking resources, making it virtually impossible to exploit a Gunners rearguard that has little right to lay claim to huge improvement.
Once Luka Modric or Rafael van der Vaart struck fear into Gooners anxious to maintain the upper hand.
Even Jermain Defoe was more a reliable goalscorer than Roberto Soldado or Harry Kane.
With little in the way of attacking signings through the door to keen the blade of Pochettino’s attack a maintaining of the status quo seems unavoidable.
