Tottenham midfielder Lewis Holtby says he won't be fazed facing Arsenal in today's derby.

Holtby has tasted what he describes as "the mother of all German derbies" and is more than comfortable in such an atmosphere.

"I've played for Schalke at Dortmund, which is the derby in German football, in front of 80,000 fans and won," said the midfielder to the Mail on Sunday.

"A game like that can get very emotional but it's important to keep cool, stay grounded and not make any dodgy tackles."
