McLaren optimistic upgrades will work

McLaren says it needs a 'good, clear session' of Friday practice in Korea to get fully up to speed with its latest upgrades, but is optimistic that it will be able to run the new rear wing that it shelved at Suzuka. The team has mounted a ferocious development effort to try and get back on terms with Red Bull and Ferrari in the title battle, but was unable to run everything it had hoped in Japan due to the track time lost to Lewis Hamilton's practice crash and the Saturday downpour
