Formula 1: Sebastian Vettel and Fernando Alonso on Ferrari switch
Ferrari's Fernando Alonso and Red Bull's Sebastian Vettel speak about the emotional end to their careers at their respective teams.
Alonso will leave Ferrari at the end of the season after five years at the Italian team, with Red Bull's Vettel replacing him. It is not certain where Alonso will drive next year, and the Spaniard has been tight-lipped about his plans.
Meanwhile, Vettel is saying farewell to the team he won four back-to-back world championships with, having been with them since he was 12-years-old.
