It has been a stellar season for the second-rower, as he helped Wigan to the Challenge Cup final by scoring in the 38-6 demolition of Hull KR in the semi-final and also played in the Wembley showpiece as they beat Sam Burgess’ Warrington.
Nsemba, whose uncle is former Liverpool and Cameroon footballer Rigobert Song, followed up those efforts with a call-up to England’s 31-man training squad for their two-match autumn Test series against Samoa.
The Wigan academy graduate’s latest deal comes less than 12 months after he committed to a further four years with the club and for the time being he is showing no signs of having his head turned elsewhere.
“At the end of the contract I’ll only be 25 or 26 so I could have a decision to make,” he added.
“But I’m happy where I’m at right now. Wigan treat all their players really well from academy to scholarship to seniors. The culture is really big at Wigan.”
