Dan Purvis may have been a late replacement for this weekend's World Cup in Stuttgart, Germany, but he insists that he is not there simply to make up the numbers.

The Scot, in for the injured Japanese Kohei Ochimura, finished last year as the world No.1 and has since gone on to help Great Britain win European team gold and Olympic team bronze in 2012.

He has returned to international competition in recent weeks and won a silver medal at the Joaquim Blume Trophy in Barcelona earlier this month and also starred in last weekend's Goodbye to London Gala in France.

He will be up against Marcel Nguyen, Germany's Olympic silver medallist, and he approaches it in buoyant mood. "I am confident that, if I get through my routines without mistakes, I will be on the front line," he said.

Nguyen has taken over the German spotlight from two-time world championship silver medallist Philipp Boy, who is expected to announce his retirement tomorrow.

Also competing in Germany will be fellow-Scot Dan Keatings, who was left out of the Olympic squad but will take part in the team event.
