Italy’s forwards bludgeoned Canada into submission and restored some order to the Rugby World Cup by scoring seven tries in a 48-7 victory in Fukuoka which catapulted them to the top of Pool B on Thursday.

It was the second successive bonus-point victory for Conor O’Shea’s side after a 47-22 win over Namibia last Sunday and all but assured them of third place in a pool that includes heavyweights New Zealand and South Africa.

They have 10 points but still need to face the All Blacks and Springboks, who are expected to qualify for the quarter-finals, short of an upset of the magnitude of Wednesday’s win for Uruguay over Fiji in Kamaishi.

The Italians, who rested several players, were in no mood to allow a second shock within the space of 24 hours and were led by rampaging loose forwards Jake Polledri, Braam Steyn and Sebastian Negri.

For the first 15 minutes they demonstrated that the gulf between tier-one and tier-two nations was still in existence, with Steyn and captain Dean Budd exploiting some poor defence to give their side a 17-0 lead by the 13th minute.

Negri extended the lead after halftime when he also smashed over from close range then referee Nigel Owens then awarded a penalty try that secured the bonus point for the Italians before replacement winger Mattia Bellini also crossed with about 20 minutes remaining.

Owens created some controversy when he awarded Tyler Ardron a try only for the television match official Rowan Kitt to rule it out for a knock-on before the ball landed in the No.8’s hands.

The decision was met by a chorus of boos but the crowd, now firmly behind the Canadians, rose to their feet minutes later when the underdogs scored the best try of the match with a superb finish by winger Andrew Coe.

Italy, however, finished strongly, with replacement hooker Federico Zani shunted over from a driving maul before Bellini put Minozzi in to close out the scoring.
