Nico Rosberg's calmness under pressure as the Formula One title race comes to a climax has impressed Mercedes boss Toto Wolff.
The German holds a 12-point lead over team-mate Lewis Hamilton going into the final race of the season in Abu Dhabi, and only needs a podium finish to secure his first championship.
Following his win in Japan, Rosberg only needed to finish second in every race to be crowned champion, a feat he has managed despite Hamilton winning all three to apply added pressure.
Watching his two drivers battle it out for the title has been tough at times for Wolff but he was full of praise for the way both men have handled themselves.
"It's remarkable how the drivers have managed the relationship between the two of them in the circumstances of a title battle," he told a media conference.
"Nico is dealing with the pressure very well. It's been like nothing affects him this year.
"When he's had a tough weekend he's kept his feet on the ground and that's been key to him keeping the Championship lead."
Meanwhile, two other drivers both part of the Mercedes family look set for drives with other teams next season.
Esteban Gutierrez and Pascal Wehrlein have driven for Haas and Manor this season, and Wolff confirmed the pair will continue their learning away from Mercedes in 2017.
He added: "Esteban is now off to Force India and we are in discussions with Sauber and Manor for Pascal."
