Melbourne Storm players charged up for World Club Challenge clash with Rhinos Storm halfback Cooper Cronk. FREEZING temperatures, days on a plane and early-morning wake-ups for drug tests have failed to dampen the spirits of Melbourne Storm players out to re-take their World Club Challenge title. After nearly two weeks in the UK, Storm coach Craig Bellamy has settled on a 19-man squad to take on Super League champions the Leeds Rhinos at Headingley early tomorrow morning. Giant young backrower Tohu Harris will make his debut as could Kenny Bromwich, younger brother of prop Jesse, who was named on an extended bench. Victorian Mahe Fonua will start on the wing with a chance to seal a berth on the backline for Round 1. Storm halfback Cooper Cronk, who missed Melbourne's 2010 WCC win through injury, said conditions could determine the final make-up of the team with the possibility snow could fall during the game and the temperature could drop as low as 1C. "There's a bit of confusion about the Leeds team and the conditions, too," Cronk said. We have trained a few times and it has been mixed and matched, a bit of movement on the ground, a slow surface. We'll train at Headingley and get a feel for the surface, whether it's muddy, whether it will be an up-tempo or slow-tempo game and make up the team after that. The game will be played on a revamped surface, with underground heating expected to ensure the snow that covered the pitch last week has gone. While in the UK, players have mixed their time between training, sightseeing and catching up with sporting champs including Mark Webber and Manchester United great Ryan Giggs. Cronk said that made the tour a worthwhile affair but the match was always the focus and Storm was desperate to win. "The boys have seen the sights, but have narrowed in their focus in the last couple of days," he said. Teams put plans in place to be peaking for this first game of the year. We are asked to be at our best with limited preparation but that's not an excuse, it's a challenge and I'm looking forward to it. Storm has clashed with Leeds twice in the WCC, with a win for the Rhinos in 2008 and one for Melbourne in 2010. "It's like an Origin series," he said. It's 1-1 now and whoever wins this wins the series.
