Although Nico Rosberg has been put on a brave face this season, Toto Wolff says that does not means rolled over for Lewis Hamilton.
As Hamilton stands on the brink on winning a third World title, which he could wrap up this Sunday in Austin, the Mercedes driver has spoken of how "good" his team-mate has been in defeat.
He added: "I just want to mention too what a great team-mate Nico is. He's had a much tougher season so far than I have but has been a real team player throughout."
Wolff, though, says being a good team player must not be confused with a driver who just gives up.
He told ESPNF1: "I think you need to be careful and not confuse two things. It's one thing being good in defeat and there is another in being very competitive, not being good in defeat but not showing it.
"I think none of the guys out there are good in defeat, but some of them are very good at containing that within themselves and not wearing their heart on their sleeves.
"Whether that is good or not is a different question, and I think he is still very upset and annoyed if he loses and very annoyed that he has probably lost the championship, but he is very professional towards the team and media in putting on a brave face."
Hamilton needs to outscore Rosberg by two points and Sebastian Vettel by nine on Sunday to clinch title number three.
