Formula One world champion Max Verstappen took stock of his new status on Monday and revealed that Mercedes team boss Toto Wolff, despite threatening to appeal, had texted his congratulations.
The 24-year-old handed Red Bull their first title since 2013 in Abu Dhabi on Sunday when he overtook Mercedes' seven times world champion Lewis Hamilton on the last lap of the final race of the season.
Mercedes had two protests dismissed but have signalled they intend to take the matter further.
Hamilton and his father Anthony congratulated Verstappen and father Jos after the race but Wolff stayed out of sight.
