Australia captain Steve Smith has criticised the arguments of Cricket Australia (CA) in the ongoing pay dispute between the players and the board on the eve of their first match in the ICC Champions Trophy.

The CA has argued that it cannot increase the players' current salaries as more money is needed to fund the game at the grassroots. 

Smith, however, challenged the CA's statement, asserting that the players have chipped in with significant contributions to the grassroots programmes.

"I'm not sure I completely agree with that. If we look back at the last MoU I think players gave back $10 million to grassroots cricket, which is quite significant," Smith told the media here on Thursday.

"We're right behind (the CA) and what they are trying to do for the players and as partners of the game as well. We fully support them in everything they are doing," he added.

Australia had a poor start to their campaign in the last edition of the Champions Trophy in 2013 when they had lost to England in their first match before crashing out in the group stages.

Smith is keen to avoid a repeat this time round and reiterated the importance of focusing on the job at hand and not giving too much thought to the off-field issues.

"We are focusing on this tournament. These are the big tournaments and the ones you really want to win," he said. 

"So my focus is on that and I'll let the CA handle everything else.

"Every game is crucial and we have got to be at our best from ball one," he added.

Smith also hinted at pace being his primary weapon in Australia's opening match against New Zealand which comes as no surprise considering the quality of resources at his disposal.

Although Smith stated that the playing XI would not be settled until the final training session, there is a chance that the four pronged pace battery of Australia comprising Mitchell Starc, Pat Cummins, James Pattinson and Josh Hazlewood could be seen in action together for the first time. 

The only selection dilemma in an otherwise settled batting line up is who amongst Glenn Maxwell and Chris Lynn will get the nod to fulfil the finisher's role.

"If it is good batting and the sun is out hopefully we can put a bit of pressure on those guys and try and play the way we did in Australia," Smith said.

Although Australia have won nine out of their last 10 encounters against their trans Tasmanian rivals, Smith feels that it will be naive to take the Black Caps lightly considering the resurgence in the fortunes of the team in the past three to four years.
