SAINTS skipper James Roby will make sure he savours every moment of Saturday's Challenge Cup Final given it could potenitially be the last time plays at Wembley.

The vastly experienced 35-year-old England hooker has a great tradition at the national stadium, going back to featuring in the Under 11s schoolboy curtain-raiser in 1997 and then scoring the first try at the new-look national stadium 10 years later.

Saturday's clash with Castleford will be his fifth Cup final appearance - having won the first three.

He said: "I know this could be my last chance and I'm going to try my best to savour it, but at the same time I don't want to enjoy it too much because I've got a job to do.

"It's fair to say that, at the back end of my career, you never really know many more finals you're going to get to, so you've got to make the most of it."

Roby's first was in the Grand Slam season of 2006 and the Blackbrooker helped his home-town club complete a hat-trick of Cup final victories with a 28-16 win over Hull in 2008.

Back then it would have been incredible to imagine Saints still waiting to add to that tally.

And is now the only player on Saints books with a Challenge Cup winners medal.

"As a young player, I came into a team that was very successful and I probably took success for granted," he said.

"We were riding that crest of a wave for a few years and I just thought this was going to continue.

"We're aware we've not won this one for a number of years, it's in the back of everybody's minds. We've put ourselves in a strong position to accomplish that and we've got to finish it off now."

Saints were surprise losers to Warrington in the 2019 final, but Roby hopes his side's back-to-back Grand Final triumphs since then can help get them over the line this time.

"That experience should help you in theory and I'd like to think that will apply to us at the weekend," he said.

Saturday's match has been designated by the Government as a pilot event in the battle with Covid-19, so 45,000 fans will be allowed to attend and Roby says that has added to the excitement.

"It's going to be amazing," he said. "It's been great just getting the 4,000 we've been allowed here at the stadium, but to go down to Wembley and play in front of 10 times that, it will be such a refreshing change.

"It's going to be brilliant for us as players and we'll really feed off the atmosphere."
