LONDON, England - McLaren boss Martin Whitmarsh is confident his team will be far more competitive in next weekend's (April 12-14, 2013) Chinese Formula 1 GP than it was in the two season-opening races in Australia and Malaysia.Whitmarsh said the team had identified some initial solutions to its problems in the break since the Malaysian race on March 24.USEFUL BREAKHe said: "Clearly, our performance in Australia and Malaysia fell below the high standards we've come to expect at McLaren. However, the three-week break between rounds two and three has been a useful for us."We've been fully engaged in further developing our understanding of the MP4-28 and are confident of being able to implement a number of changes this weekend that will widen its operating window and, potentially, improve its performance."Jenson Button, the 2009 Drivers World champion, said that after the two poor outings he endured with McLaren he was treating the race at Shanghai as another start to the season. "In a funny way, the Chinese GP almost feels like something of a reboot of the start of my season. Taking home two points from the first two races obviously wasn't what we had in mind at the beginning of the year but I think everybody in the team has picked themself up and really attacked the task of addressing our car's issues."We know where we're losing performance, so I think we're actually all looking forward to seeing just what we can achieve in Shanghai. The important thing for us as a team is to go into the weekend with clear focus, hone our strengths across the sessions and increase our understanding of the car."There's everything to play for with this championship and I can't wait to get back into the cockpit to start the fight again."
