Tottenham chairman Daniel Levy scoured the sporting world in search of inspiration for the never-quite-ready-to-open new stadium at White Hart Lane and decided he would try to create something akin to Borussia Dortmund's imposing Sudtribune of the Westfalenstadion.
The 'Yellow Wall' as they call it can hold nearly 25,000 fans in a single tier stand but it is not the capacity or the design which intimidates it is the noise and energy so often generated from behind the goal which was defended by Spurs in the second half last night.

The Londoners disturbed the rhythms of the game, frustrated their hosts and Harry Kane's nerveless finish stunned Dortmund into silent surrender. It was an immaculate European performance in every sense and three-and-a-half thousand fans started to celebrate.
