Morgan Escare added the French polish to their derby triumph by revealing he has signed a new contract with Wigan.
The full-back arrived in the off-season on a one-year deal after being released by Catalans.
But he has agreed to stay for three more years, with an option in the club’s favour for 2021.
He revealed the news on social media after the 29-18 Good Friday win against St Helens.
“I am really happy here at Wigan and feel at home,” said the 24-year-old. “The fans, players and coaching staff have been great with me and I am really enjoying it here.
“I’m enjoying my rugby too and am happy with the way I am playing. It’s great to have this new contract agreed and I am excited for the future.”
Escare, a French international, has been sensational in his 10 matches so far and proved a more than capable deputy for injured Sam Tomkins at full-back.
Tomkins, the club’s marquee player, has not played this year because of a broken foot and is only expected back around June.
Coach Shaun Wane said: “Morgan is great to work with and the best thing is I don’t think we’ve even scratched the surface with him yet. He’s a talented player but there is so much more to come from him.
“He’s fitted right in at Wigan and we’re delighted that he’s going to stay here.”
Escare’s announcement came less than 48-hours after England stand-off George Williams pledged his future to his hometown club, which suggests Wigan are working through their contracts for 2018 and beyond.
Captain Sean O’Loughlin and forwards Taulima Tautai and Joel Tomkins are all off-contract at the end of this season.
O’Loughlin has an agreement to move onto the coaching staff when he hangs up his boots, but has previously indicated he wants to play on, while Tomkins last week spoke of his hope to stay.
Speaking about Escare’s new deal, rugby director Kris Radlinski said: “He came here with a desire to prove people wrong and has worked very hard, along with our coaching staff. He feels at home here, he’s learning ‘Wiganese’, and the Wigan fans have really taken to him too.”
