Lewis Hamilton showed his fellow Formula 1 drivers no mercy on Sunday despite already being World Champion, as he won the Abu Dhabi Grand Prix.
Having wrapped up his fifth crown in Mexico, the Brit strolled to yet another win in the desert by keeping teammate Valtteri Bottas and Sebastian Vettel at arms length.
It's been another sensational season for Hamilton and his Mercedes team, who also secured the Constructors' Championship, with Vettel and Ferrari unable to find an answer for their dominance.
And Hamilton has vowed to return even stronger in 2019 as he aims to defend his title and win three in a row as a result.
Whilst Hamilton is at the pinnacle of his career, another of F1's all-time greatest drivers Fernando Alonso has called time on his this year.
The veteran Spaniard enjoyed a strong start in F1, winning back-to-back championships with Renault in 2005 and 2006, and seemed set to win more championships as he joined McLaren in 2007.
But, his spell with the team turned sour, as he clashed with young prodigy Hamilton and team principal Ron Dennis.
With the team at war, Ferrari's Kimi Raikkonen was able to steal the title from under their noses.
Alonso eventually joined Ferrari, but was still unable to win a third World Championship due to Red Bull's period of dominance with Vettel.
It's been a sad end to Alonso's career, as his gamble to rejoin McLaren has ultimately backfired, whereas Hamilton's decision to join Mercedes after leaving McLaren has taken his career to the next level.
This was highlighted by the contrast between Hamilton's dominant win and Alonso toiling at the back of the grid, as he has done all season in a sub-par car.
Even though he has had his struggles with McLaren, Alonso is still recognised as one of the best drivers of all time, who has been able to squeeze more than most would out of a poor set up.
And, despite their championship-busting fall-out over a decade ago, relations between Hamilton and Alonso have thawed over recent years and the pair have a mutual respect for each other.
The two haven't crossed paths too much recently due to being in competitive cars at different times, a factor which has probably helped the process.
After the race finished, the pair even took part in the customary doughnuts alongside Vettel.
Hamilton then took to Twitter to pay tribute to his fellow driver, saying: "Farewell Fernando, it has been a pleasure."
Alonso then replied with, "Good luck champ."
Certainly short and sweet from both, but at least they've ended things on a good note, despite not being overly congratulatory.
Whilst Hamilton will strive to win more F1 championships, Alonso is exploring other options in motorsport, and took part in a NASCAR race straight after finishing his F1 drive in Abu Dhabi.
