MONZA, Italy (Reuters) - Felipe Massa, the Brazilian who almost won the Formula One championship for Ferrari in 2008 before Lewis Hamilton snatched it away at the last corner of the final race, is to retire at the end of the season.

The 35-year-old Williams driver, who won 11 grands prix for Ferrari between 2006 and 2008, is out of contract at the end of the year and said he had decided some months ago that this season would be his last.
