Ferrari's Felipe Massa thought about quitting Formula 1

Ferrari driver Felipe Massa reveals he thought his F1 career was "finished" after he endured a difficult start to the 2012 season.

The Brazilian was off the pace of team-mate Fernando Alonso in the first half of the year but ended strongly, even outpacing the Spaniard occasionally.

Massa says he is now full of confidence going into the new season and feels the team is in good shape for a successful year.
