Sheens wary of imploding England at RLWC Kangaroos coach Tim Sheens is determined not to let England's troubled Rugby League World Cup build-up cloud Australia's focus ahead of their tournament-opening clash. England appear a team in disarray ahead of Saturday's (Sunday morning AEDT) encounter in Cardiff, with coach Steve McNamara walking out of a press conference on Friday after refusing to speak about prop James Graham's controversial omission from the squad. It continued a tumultuous build-up for England, who suffered a shock loss to Italy in a warm-up match and axed Gareth Hock for the tournament after he broke a team alcohol ban. Sheens did not want to be drawn into the dramas but warned they could in fact galvanise Australia's opening Pool A opponents. I'm not particularly interested in it. All I'm worried about is us," Sheens said before his side trained at Millennium Stadium on match eve. They've got their reasons for whatever but our main focus today is about Australia. The only comment I'll make is that an embarrassed side is a dangerous side. Anyone who's been involved in sport understands when things go wrong it can have the exact reverse effect. Our main aim again is to ensure our game is right, that we do what we need to do, and not expect anything from England but a Test match. Graham is thought to have been dropped for the match against Australia for also breaching the alcohol ban but Sheens said the blow would be offset by the return of Warrington forward Ben Westwood, who missed his side's friendly defeat by Italy through suspension. "Westwood comes into the side and he does exactly the same (as Graham)," Sheens said. Earlier on Friday, a cagey McNamara refused to answer questions about Graham's omission in a tense press conference he ended after little more than six minutes. "There's seven very good players not playing this week," McNamara said when asked to clarify the decision. I'm not going to talk about any individual players. Those seven are all great players, great people and I'm sure they'll get to play a part in the rest of the tournament. Pressed further on the issue, McNamara became agitated. "Look, I just said I'm not going to talk about any individuals," the coach said. I'm not going to answer any more questions on it and if you want to continue asking questions on it then we'll wrap it up now. McNamara walked out when when asked if Hock's exclusion from the squad was also off-limits. Of course it is. I've got to go anyway boys because the bus is going. See you tomorrow," he said. Despite the dramas, McNamara says he has strong belief in his players and is confident they will perform well against the Kangaroos. The coach named a 19-man squad for the game and has opted not to reveal his final 17. Tom Burgess is one of the players likely to be cut, denying him a chance to play alongside brothers Sam and George.
