Gareth Bale has been crucial to Tottenham's recent success against Arsenal, scoring three times in the four derby wins he has enjoyed since moving to White Hart Lane six years ago.
But, for the first time in the derby for four years, Bale will not be in Tottenham's starting XI on Sunday because of his impending move to Real Madrid.
Yet with the vast spending spree that has taken place at White Hart Lane this summer, there is optimism within the Tottenham squad, especially as their north London rivals are yet to spend a penny in the market despite vast cash reserves being available to manager Arsene Wenger.
Andre Villas-Boas' team have coped fine without Bale so far, registering four straight wins without conceding, but former captain King knows talk of a shift in the balance of power will be premature unless his old team manage to pull off a win at the Emirates Stadium.
"The players have been brilliant so far this season and the club have brought in top-class signings so this weekend it's a big game, one to show who is the dominant force," King said at the launch of Vodafone 4G.
"We are looking to go there and prove that we are a stronger side."
Throughout his 13-year spell at Tottenham, King did not once feature in a north London derby win away from White Hart Lane as he missed the 2010 victory at Arsenal through injury.
More importantly, the former captain did not see his team finish above the Gunners in the table throughout his time at the club.
Spurs have thrown away significant leads over Arsenal in the last two seasons and they have finished below their rivals every year since 1995.
