We've yet to see best of Vettel, warns Red Bull boss
(REUTERS) - Sebastian Vettel has been backed by his Red Bull principal to get even better as a driver having become the youngest triple Formula One world champion in the season-ending Brazilian Grand Prix on Sunday.
Mr Christian Horner, who also said McLaren would be weakened by Briton Lewis Hamilton's departure to Mercedes, was full of praise for German Vettel as the Red Bull team arrived home to their Milton Keynes base in England on Tuesday.
"I think as his experience grows, he is continuing to grow as a person. We've yet to see the best of him," Mr Horner told reporters of a 25-year-old he describes as "amongst the greats".
The ominous warning to Red Bull's rivals came after the team clinched the driver and constructor world titles for the third year in a row.
