SYDNEY ROOSTERS became the most successful side in the World Club Challenge thanks to a hard-earned victory against St Helens on Saturday night.

It is the reigning NRL champions’ second consecutive win in the competition, and meant they joined Wigan on a total of four victories in these international club matches.

This latest triumph, against last season’s Super League Grand Final winners St Helens, also maintained the Roosters’ 100 per cent record in the tournament, with their first triumph having come against the same opposition back in 2003.
