SAO PAULO, Brazil - Mark Webber is not ready to spill the beans on the intriguing story of his "fuckng intense" title battle with Sebastian Vettel in 2010 but has hinted there was much more to it than meets the eye.The about-to-retire Red Bull driver was referring to 2010, the year in which he famously exclaimed "Not bad for a No.2 driver" after winning the British GP. Webber (37) told the UK's Daily Telegraph: "Only those closest to me know what went into it." Asked if the truth would eventually come out, he insisted: "Not from me. Looking back I'm pretty proud of myself, the way it was kicking off and how I handled myself."LONG-TERM SAGASilverstone was the epicentre of the fraught campaign, when a newer spec front wing was taken off Webber's car and put on eventual champion Vettel's but there was also the collision in Turkey and Telegraph correspondent Tom Cary suggested Webber's once-close relationship with Red Bull team boss Christian Horner never fully recovered after the goings-on of 2010.Webber conceded: "To manage the whole scenario hasn't been super easy for the team. We were in uncharted waters in 2010. 'Fuck, we're going for our first title. Holy shit, how do we do it? Let them both go at it maybe? Oh no, maybe not."Webber's relationship with Vettel only nose-dived further in recent years, culminating in the notorious 'Multi-21' affair of early 2013 and eventually the veteran Australian's decision to retire and move to Le Mans.Referring to 'Multi-21' and the loss of the Malaysian GP victory this year, Webber said: "There are blinkers and there are blinkers. I saw Michael (Schumacher)'s blinkers, too, and I don't think Seb's are as bad as that. I think in time, a stiff glass of red wine one day down the line, it will probably be OK with us, but it's hard at the moment."Some of Webber's closest paddock allies will wear T-shirts bearing the slogan 'Made My Mark' to say farewell the retirement of the popular driver from Formula 1.
