Retiring Jamie Peacock relaxed as he chases ninth Grand Final victory

Jamie Peacock is preparing for his final game of rugby league

Retiring prop Jamie Peacock says Leeds are drawing on past experiences as they target a sixth win on as many visits to Old Trafford in Saturday's Grand Final against Wigan.

The Rhinos left Manchester with the Super League trophy on five occasions between 2007 and 2012, giving Peacock a record haul of eight winners' rings.

The 37-year-old insisted those successes give Leeds an edge ahead of a repeat of the inaugural Grand Final in 1998.

"When you win a final you have that muscle memory - you know what to do and how your mindset was during the week and during the game," said Peacock, who has also won four Challenge Cups in his decorated career.

"It's a huge lift to yourself and the team. It's something we've been able to fall back on year after year when we've got to Grand Finals.

"We've had that ability to win no matter what situation we've been in within the Grand Final and I think that will be big for us on Saturday."

Leeds booked their place in a first Grand Final in three years with a tense 20-13 victory over reigning champions St Helens last Friday, a play-off semi-final which gave the Rhinos fans the chance to say goodbye to Peacock, Kevin Sinfield and Kylie Leuluai.

The outgoing trio would have missed out on a Headingley farewell but for a late comeback win over Huddersfield which clinched the League Leaders' Shield, and Peacock admitted those back-to-back successes have taken the edge off his anxiety.

"I wanted to win my last game at Headingley and come here and play at Old Trafford so I think there was a lot of pressure on," said the former Great Britain and England captain.

"That's kind of off this week because I know what's happening; I know it's Old Trafford and this is it. The pressure is a little bit less this week."

The Grand Final represents a chance for Leeds, who retained the Challenge Cup in August, to complete the treble for the first time in their history, a feat which would set the class of 2015 apart from any other side Peacock has played in.

"I've been really lucky to play in some great sides in all my career, but if we win the treble I think it'll be the best," he added.

"It's more difficult to do now than ever before because there's more than one or two good sides."

Standing in the Rhinos' way are a Wigan team that finished second in Super League and are desperate to avoid a repeat of last year's Grand Final heartache against St Helens.

"We've been the best two sides all year so it's good to see us both at Old Trafford," Peacock said ahead of his 552nd and final appearance.

"There's some pressure on Wigan after what went on last year; a lot of people said they'd have won the game if the incident (Ben Flower's red card) hadn't happened.

"It's up to them to deliver a big performance but we're standing in their way. It's the same for us; we want the fairytale finish but we know there's an incredibly good side in front of us."

It will be a case of digging deep one last time for Peacock, who insisted energy will not be a problem at the end of a gruelling season and career.

"There's enough left in the tank because this is it," he said.

"The reality is that I'll wake up on Sunday morning and I won't be a rugby league player so I'll be giving it absolutely everything I've got."
