WATCH: Say What? Tears, farewells and plenty of singing – the best team radio clips from Abu Dhabi
The Abu Dhabi Grand Prix was the final outing for a number of drivers up and down the grid before they switch teams for next year, or leave Formula 1 altogether.
Sebastian Vettel is swapping Ferrari for Aston Martin, while Carlos Sainz is leaving McLaren to take Vettel's seat at Ferrari, and Daniel Ricciardo is slotting in at the Woking team, after two years with Renault.
All three took the opportunity to say their goodbyes over team radio after the race in Abu Dhabi, as did Kevin Magnussen, who is leaving Haas to go racing in the USA next year.
There were tears, farewells and even outbursts of song over the airwaves at the Yas Marina Circuit – and you can hear all the best moments in our team radio round up in the video above.
