Sebastian Vettel admitted he feels "liberated" since telling the world he will retire from Formula 1 at the end of the season.
The German's F1 career, which has yielded four world titles and 53 race wins, ends after this year's Abu Dhabi Grand Prix. He will be replaced at Aston Martin by an even more experienced driver, in the form of 41-year-old Fernando Alonso.
Since announcing his retirement, shortly before the Hungarian Grand Prix in July, Vettel said he feels like a weight has been lifted off his shoulders. He was able to enjoy the summer break, and recharge ready for one last push in the final few months of his last-ever F1 campaign.
