If you want pure entertainment on Saturday, forget about Big Brother, Who Dares Sings! or Casualty.

A higher class of performance will be on show at the Galpharm Stadium, with the two most entertaining rugby teams in Britain - of either code - meeting in one of the most eagerly anticipated Challenge Cup semi-finals in years.

With 304 tries between them already this season, St Helens (with 165) and Leeds (a mere 139) are setting new standards in attacking rugby league and their respective prolific wingers Scott Donald and Ade Gardner are enjoying every minute.

The two deadliest try-scorers in British rugby league will come head to head and Gardner - the top try-scorer in Super League - is under no illusions about what is at stake.

"It will be a special game and in terms of the hype, this is probably one of the biggest games I've played in during my career," said Gardner, who has numerous Grand Final, Challenge Cup finals and Test matches under his belt.

"You can get sense what a big game this is. There's a real buzz about this game, and it's built up in the five or six weeks since the game was drawn out the hat.

"I can just see it being an epic."

He's somebody who you can't give any space to whatsoever because he can be past you in a blink of an eye Ade Gardner on Scott Donald He's not sitting on the top of the try-scoring table for nothing. He always puts in consistent performances and it's very rare you see him have a bad game Scott Donald on Ade Gardner

Gardner has crossed the try-line 24 times for St Helens this season, not to mention his hat-trick against France for England in June, but the 25-year-old is keen to share the credit for his feats.

"Playing outside (Saints centre) Matt Gidley makes my job a lot easier," Gardner told BBC Sport.

"It's not just him - there's a lot of good work goes on before the ball gets to him - but some of the passes he has given me for tries this year have been absolutely unbelievable.

"Some of them, I think only he could do. He's a legend of the modern-day game with his ability on the ball."

Donald, who arrived at Headingley from Manly Sea Eagles back in 2005, also expects Saturday's game to be something special.

"It's a huge game, probably the biggest of the year so far for us. It's something the whole club is really excited about," Donald told BBC Sport.

"Over the last two years I think it's fair to say that Leeds and Saints have been the best two teams. It's going to a game that could go either way.

"Both teams have been in some very big matches and the more you play in those sort of games, the more you get used to it."

Donald, only three tries behind Gardner in the statistics, is similarly grateful to be playing alongside talented team-mates.

"Having the likes of Rob Burrow, Danny McGuire and Brent Webb on your side makes it a joy to play on the wing in this Leeds team," he said.

"There's no stage of a match when we think we can't win: we always have a chance when you have players of that calibre to call on.

"And it doesn't matter where we are on the field or the time of the game - we can score from anywhere and that's one of our greatest strengths."

Donald should know what to expect against Gardner, with a custom-made DVD of his opposite number forming a major part of his viewing this week.

St Helens have not lost in the Challenge Cup since 2005

"It's good to be able to look at what your opponent has done in the past, whether he tends to favour a step to one side or always tries to offload. We do our homework on the opposition and I'm sure they'll do the same for us."

St Helens have won the last two Challenge Cup finals, with their last defeat in the tournament coming against Hull FC in the 2005 semi-final.

"We'll take some confidence from our winning run in the tournament but it's all about what happens on the day," added Gardner.

"The Challenge Cup is such a difficult competition and it has so much history and I know Leeds are going to be revved up.

"They haven't been to a Challenge Cup final for a few years and they haven't won one for even longer so they will be fully focused. We're the champions of this competition and we don't want to give up the trophy by any means."

Donald, meanwhile, has got motivation of his own for making it through to the final against either Wakefield or Hull.

"I've never been to Wembley before. To be honest, I've never even seen it," he said.

"I think (veteran Leeds centre) Keith Senior - who is a dinosaur - is the only one in our team to have played there so we're pretty keen to get there. It would be amazing to walk out on that Wembley pitch."
