British officials are convinced the World Club Series will continue despite their NRL counterparts snubbing the competition by remaining in Sydney as Super League sides scored a stunning clean sweep.

Wigan are rugby league's new world champions after a grinding 22-6 win over Cronulla at DW Stadium on Sunday, the famous club lifting the trophy for the first time since 1994.

The previous evening, Warrington's Kevin Brown said that game 23 years ago had inspired him to take up the sport, after he was man of the match in a 27-18 win over Brisbane.

Super League's Roger Draper had told Fairfax he had hoped to lock in the 2018 series over the next fortnight; four NRL teams had refused to take part before Brisbane accepted and it was scaled down from six sides in 2015 and 2016 to four this year.
