ESPN rounds up the best radio soundbites from the 2015 season finale in Abu Dhabi.

"Who was in front of me in the last three corners?"

"Stevens and Grosjean."

"Idiots!"

Fernando Alonso fumes at the driving of Will Stevens and Romain Grosjean after being held up at the final sector during a lap in FP3.

"The plan was to let him through, right?"

Sebastian Vettel has a moment of doubt after moving over to let Ferrari team-mate Kimi Raikkonen past him midway through the race.

"I'm a bit busy here!"

Daniil Kvyat responds to a list of instructions from Red Bull with an irritated reminder he has other things to worry about like driving a Formula One car.

"Alonso in front of you, blue flag."

"I mean he must really hate me, I don't know what's wrong with him. I'm losing a second just because of that."

Vettel questions Fernando Alonso's reluctance to let his old car past in Abu Dhabi despite being a lap down, suggesting the Spaniard's hostility towards him was a factor.

"If we do not have a safety car I will retire the car."

Alonso's mindset is probably best explained by this radio message, where he seems willing to throw the towel in on the race and the 2015 season as a whole half a race early. He eventually changed his mind and raced to the finish.

"Strat mode 10, strat mode 10. That's an instruction"

Mercedes' pit wall becomes slightly irritated with Lewis Hamilton during a bizarre exchange of radio messages at the end in an attempt to maintain some form of battle out in front.

"Wonderful guys. Thank you so much for everything we have been through. I'll miss you, I love you, and I do hope we work together again!"

Ever the gentleman, Romain Grosjean signs off his Lotus tenure with a ninth place and a heartfelt message of thanks before his 2016 switch to Haas.

"That was fun, hey? We have a few weaknesses but we know exactly what to do and we can do it guys. It's going to be a long winter -- but a good winter."

Jenson Button signs off McLaren's horrendous 2015 campaign with a battle cry and promises the team the only way is up over the winter.
