Helmut Marko admits being the one who told Mercedes that Lewis Hamilton could be poached from McLaren.
The seven-time world champion won six of those trophies following his switch to the Silver Arrows. He first became a title-winner with McLaren in his second year as a Formula 1 racer, after narrowly missing out in his debut campaign.
But following his 2008 triumph, opportunities for Hamilton to summit the F1 world again were limited. His frustration over that fact was a major part of the reason why he made the shock decision to leave for Mercedes in late 2012.
