TIMMY MURPHY believes Irish raider Wild Passion will be the main threat to his mount Marcel in today's ladbrokes.com Tolworth Hurdle.

WILD PASSION arrived safely at Sandown yesterday from Noel Meade's yard in Co Meath and is all set for his big head-to-head with Marcel in the ladbrokes.com Tolworth Hurdle at the Esher track tomorrow.

Expect the Paul Nicholls-trained Silver Birch to run a huge race in the £100,000 (€142,100) Coral Welsh National tomorrow if the holiday card at Chepstow beats the freeze.
