<P> The 2013 season saw new staff , a new coach , Trent Robinson , and several new players , including big signings Michael Jennings , James Maloney , Luke O'Donnell and Sonny Bill Williams , arrive at the club . This culminated in the Roosters finishing the 2013 season with a 24 -- 12 win over the South Sydney Rabbitohs , securing the minor premiership for the 2013 season and were the NRL 's best attacking and defensive team . The Roosters defeated the Manly - Warringah Sea Eagles 4 -- 0 , in week one of the finals , earning a week 's rest . The Roosters defeated the Newcastle Knights 40 -- 14 in week three of the NRL finals , progressing to the 2013 NRL grand final , facing the Manly - Warringah Sea Eagles , winning 26 -- 18 . It was a great comeback by the Roosters , down by 10 points in the second half they went on to score three consecutive tries to seal the win and their 13th premiership . They then went on to win the 2014 World Club Challenge against Wigan 36 -- 14 to claim the treble of club titles . No team in premiership history had come from a lower ladder position to win the following season 's title . </P>
