Button must rid himself of complacency, says Mansell

NIGEL MANSELL has warned the misfiring Jenson Button to keep his composure if he wants to become Britain&rsquo;s second successive Formula 1 world champion.<br /><br />The Brawn driver remains on course to follow in the footsteps of fellow countryman, and last season&rsquo;s winner Lewis Hamilton, holding a 16-point advantage with five races remaining.<br /><br />But after going five races without a win, Mansell, another former British world champion, believes Button is in real danger of cruelly missing out on the title after falling foul to complacency.<br /><br />&ldquo;I think he needs to shake himself up a bit,&rdquo; said Mansell, speaking ahead of this Sunday&rsquo;s Italian Grand Prix.<br /><br />&ldquo;He has gone off the boil in recent races for whatever reason and at the moment you would have to say that he is being outdriven by his team-mate.&rdquo;<br />Six wins in the first seven races saw the 29-year-old race into an early championship lead, but a poor run of form has seen the wheels come off Button&rsquo;s title chase slightly in recent weeks.<br /><br />The Brit now faces stern competition from Brawn team-mate Rubens Barrichello, who, after winning the European Grand Prix in Valencia, looks set to race his partner all the way to the finish at this season&rsquo;s finale in Abu Dhabi.<br /><br />&ldquo;People react to pressure in different ways and we are seeing Jenson under real pressure for the first time now,&rdquo; added the 1992 world champion.<br />&ldquo;When I won the title I thrived on that pressure and it made me stronger, and I was determined not to loosen my grip.<br /><br />&ldquo;Jenson needs to get a grip right now because he will never have a better opportunity to be world champion. If he lets this one slip through his fingers, he&rsquo;ll never forgive himself.&rdquo;
