Flash back to when Lewis left McLaren to join Mercedes. Niki Lauder and Ross Brawn were spot on when he signed saying after 12 months they would dominate, no else believed it though
"Mercedes is a great partner of ours and they are a great team. But for anyone leaving McLaren, and he wants to win, I think that's a mistake because I have faith and belief in this team. Whether you measure it over the last four races, four years or 40 years, we're a fantastic team. So I would say to any driver who wanted to win in this sport: 'Come and join McLaren and aspire to join McLaren'. I wouldn't advise anyone to leave McLaren if they want to win" - Martin Whitmarsh, McLaren
"It is his decision, although I personally don't think it is the right decision" - Jenson Button, McLaren.
"I don't see Lewis winning races in 2013 - and there has to be doubts that the car will be good enough in 2014. And it is easy for a lean couple of years to develop into something longer. Just look what happened to Jacques Villeneuve after he joined BAR having won the title in 1997. He never won another race. Lewis has got a tough task ahead of him at Mercedes. It is a gamble" - Allan McNish, Audi.
