Lee Smith received a good-luck message from Wasps coach Shaun Edwards before going out to produce his Grand-Final heroics for Leeds in their 18-10 victory over St Helens.

The 23-year-old England centre, who is joining Wasps on a three-year contract, enjoyed a fairytale farewell with the Rhinos by scoring two of their three tries as they completed an unprecedented engage Super League hat-trick of titles, all of them at the expense of arch rivals St Helens.

Smith has played and scored in all three Old Trafford triumphs, each of them in a different position, and admits it will be a wrench to leave the club after six successful years at Headingley.

However, he insists there are no regrets over his decision to switch codes and he is looking forward to linking up with former Wigan and Great Britain legend Edwards and Wasps director of rugby Tony Hanks.

"Shaun Edwards and Tony Hanks sent me good-luck texts before the game and I appreciated that," said Smith.

"They've been really good with me. I'll catch up with them later in the week and see what they want from me.

"I'm looking forward to working with Shaun. He's an absolute legend of this game and hopefully he can tip me up on being a legend over in that game.

"It's going to be tough leaving because I've made some friends for life. The friendship means a lot to me, as much as all the trophies.

"But I'm looking forward to going to rugby union. I made my decision and I think it's the right one.

"I'll have a few days to myself, grab a holiday and then start thinking about Wasps."

Smith's first try four minutes before half-time enabled Leeds to draw level at 8-8 and his second, eight minutes from the end, finally settled a pulsating encounter, albeit in controversial circumstances.

The centre appeared to be offside from Danny McGuire's stabbed kick to the line but video referee Phil Bentham ruled in the Rhinos' favour.

"I thought I was just level," said Smith. "It's on the scoreboard and that's all that counts."

St Helens finish the season empty handed for the first time for six years but they had dominated the opening exchanges and led 8-0 thanks to 20-year-old Kyle Eastmond's try and two goals.

But Leeds' superb defence and imaginative kicking game kept them in touch and hooker Matt Diskin's close-range try on 29 minutes started to tilt the match the champions' way.

They were dealt a blow when second rower Ali Lauitiiti hobbled off but Smith's first try, courtesy of a blunder from Saints' threatening but error-prone winger Francis Meli, was a timely fillip for the Yorkshiremen.

A drop goal from man of the match Kevin Sinfield at the start of the second half edged Leeds in front for the first time and he traded penalties with Eastmond before producing a try-saving tackle on the young centre to preserve the lead.

The tension became almost unbearable until Smith pounced for the all-important try to settle nerves and Rob Burrow wrapped up the scoring with a late drop goal.

"It was a tough game and luckily we got a win," added Smith, who was man of the match 12 months earlier. "Saints brought it to us and we had to dig in. It was a cracker of a game.

"To finish at Old Trafford and get a win is absolutely brilliant. It hasn't really sunk in yet.

"This ground has been brilliant to me. Much as I support Leeds United and they don't really like Man United, this place has been good to me and I'll miss playing here."

Smith may have played his last match for Leeds but he may not yet be finished with rugby league after revealing that Wasps will not stand in his way if selected for Tony Smith's England side in the Gillette Four Nations series which get under way later this month.

"I'll see what Tony thinks," said Smith. "It's up to him. I'm available for England.

"If he wants to pick me, I'm there. I'd wear the jersey with pride. Hopefully I will be in."
