Budapest, July 30: Jenson Button believes he must finish on the podium in Sunday's Hungarian Grand Prix if his McLaren team are to maintain their lead in the world championship.
Defending champion Button admitted that results in recent races have helped his team's cause, but admitted that unless they pick up some better finishes, it is only a matter of time before their luck runs out.
"At this stage of the season we need to be fighting for podiums," said the Englishman.
"Lucky for us it has been one Red Bull fast, one not so fast and they haven't really taken too many points off us recently, but I'm sure that could change very quickly.
"The good thing is it's very competitive at the moment and we're all taking points off each other.
