Nico Rosberg move no surprise to Lewis Hamilton

Lewis Hamilton insisted yesterday he was not surprised that long-running rival Nico Rosberg has brought the curtain down on his Formula One career.

World champion Rosberg, 31, stunned the sporting world by announcing his decision to retire from grand prix racing just five days after clinching his maiden title.

But Hamilton, who has been competing against Rosberg ever since their formative racing years in karting, has claimed he was not taken aback by his Mercedes team-mate’s decision.
