Winning the Super League Grand Final in his last game as Wigan Warriors head coach was "the perfect end" for Shaun Wane.

Wigan overcame Warrington Wolves 12-4 at Old Trafford on Saturday to bring Wane's 30-year association with the club to an end in triumphant fashion.

It was the 54-year-old's third Grand Final victory since taking over as head coach in 2011.

Despite it being the ideal farewell before switching codes to take up the role of high performance coach with Scottish Rugby, Wane could not hide his frustration with the performance.

"It's the perfect end. I'm not going to put myself in a bad mood thinking about the performance because I don't have to do that anymore, that's finished, somebody else is going to do that next year," an emotional Wane said in a post-match news conference.

"I'm just happy to get the win. I don't think we were ever going to lose it, there was enough spirit and desire in the team.

"We gave them too many chances to defend our line, we turned the ball over too easy. I'm so pleased for all my staff who have put up with me for many years and I'm not easy to work with, and the players past and present have made my career special."

All eyes were on Wane at Old Trafford but the Wigan icon revealed he felt the tension surrounding his impending exit more fiercely ahead of the semi-final against Castleford Tigers.

"Last week I was absolutely so nervous because I didn't want my career to finish at home against Cas. I didn't want it to happen that night," he said.

"That week leading up to the Cas game... I don't get uptight and annoyed during games but that was a shocking week for nerves. The manner we won the game was fantastic, but this one was more enjoyable.

"I just relaxed a bit and enjoyed the game, a bit more focused. Me being with the team, we spoke honestly to each other and we've said some very touching things. It's been a special few months, uncomfortable, but it's been special."

Josh Charnley opened the scoring for the Wolves before Tom Davies touched down either side of a Dom Manfredi double, but Warrington coach Steve Price felt Sam Tomkins, who will be a Catalans Dragons player next season, should have been sent to the sin bin after tripping Bryson Goodwin and catching a prone Daryl Clark with his knees.

When it was put to him the incidents warranted a yellow card, Price responded: "Certainly. That would've been a yellow card if it was a normal game.

"They were two tough calls there. Couldn't get a win there but sometimes you don't get those calls.

He added: "It could've gone either way until the 77th minute. As I said to the boys, I'm super proud of them. We've come a long way from when we first came together in November.

"We have a backbone of a really tough, resilient football team now and that showed from some great displays throughout this season - to knock off the league leaders [St Helens] last week and give ourselves a chance right up until the 77th minute, as I said I'm super proud of the team, the club, and we'll come back bigger and better next year."
