RUDI Keil is planning to give his all-time hero a headache on Sunday when Worcester Rugby Club bid to beat Francois Pienaar's Saracens.

The South African centre, who arrived at Sixways last month, believes Worcester have a chance of moving into the quarter-finals of the Tetley Bitter Cup by causing the shock of the fourth round in Watford.

The 22-year-old cannot wait for the challenge of pitting his wits against his hero's side and the best centre in the world -- Tim Horan.

He said: "It will be phenomenal to play against the world's best centre but also to play against Francois' club.

"He is such a big hero, not just for me, but for everyone in South Africa after the 1995 World Cup. I remember him from when I was younger when he came to my High School in Johannesburg to train. It was amazing to just watch him back then."

Keil even trained with the rugby legend two years ago when he was invited to Vicarage Road by the former Springbok skipper.

He said: "I was in the country with my father at the time and spent two weeks training there. It was just a phenomenal experience to train with the players and learn off Francois. I told him my dream was to play for the Springboks and he encouraged me."

Keil, who signed from South Western District Eagles, is in no doubt Worcester face a tough test against the Premiership top dogs but is confident the National Division One leaders will be up for it.

He said: "I think it's anybody's ball game because anything can happen on the day. The important thing for us is that we are completely focussed on what we have to do. We are the underdog but underdogs sometimes upset the form.

"It is a very exciting game for the players because you always want to test yourself against the very best. For me personally, it will be a great benchmark to be playing against Horan and to see how I perform."
