Mike Hussey says David Warner's improved defence gives him chance to be world's best bat Warner, back with the Thunder. MIKE Hussey says an improved defensive technique has set David Warner up to become potentially the most dangerous batsman in world cricket. Warner returns to his bread and butter T20 form for the Sydney Thunder on Saturday night, as a player now proficient at dominating the red and white ball. After failing to win a game last Big Bash League season, the Thunder are looking for Warner to do what he does best and smash cross-town rivals the Sixers into submission at the SCG. And there's no better gun-for-hire than Warner, who will be back in whites again come Boxing Day. Warner celebrates after scoring a century in Perth. Despite the class he's shown this Ashes series, for the most part, it was a challenging 2013 for Warner. He was dropped from the Test team for poor behaviour and punted from the ODI side for poor form. But rather than kick stones, Warner's electric summer is evidence of the work he's put in. The explosive left-hander possesses the self-belief to dominate any attack, and now he has the tools to deliver more consistently. While Warner will never part with his attacking instincts, having an improved defence to fall back on has been crucial to him surviving tough periods at the crease. Warner will spearhead Australia's World Twenty20 assault in 2014, their 50-over World Cup campaign in 2015, as well as the Test team's pursuit of the coveted No. 1 ranking. Thunder teammate Hussey says Warner is a different player to the one he shared an Australian dressing room with last summer and described his potential across all three forms as "scary." Mike Hussey - impressed by Warner's defensive work. We all know how attacking he can be and the range of shots he's got. But his defence looks so solid at the moment and that's not something I could have said in the past," Hussey said. When the England bowlers have hit him hard he's been very, very sound in defence and that's what's really impressed me the most. When he's confident, there's nothing that can stop him. The Thunder were a basket case last season, but new signing Hussey says the team aren't carrying any mental scars. Inaugural BBL winners the Sixers are looking to bounce back from a disappointing 2012-13 season, and have an in-form Test player of their own - Steve Smith - to lead the way.
