Niki Lauda is confident he can restore to calm to Mercedes but only after speaking with Lewis Hamilton about his behaviour on the podium.
Finishing second behind Nico Rosberg, who won the Monaco Grand Prix after securing a controversial pole position, Hamilton's mood carried through onto the podium.
The British driver barely congratulated his team-mate and had little to say about anything in the immediate aftermath.
Lauda told Autosport: "Lewis not happy finishing second is normal, but in the end he has to accept another guy was quicker. This is very simple in racing.
"What I did not like, and I have to say, and I will tell him this on Monday, is that when you are up there [on the podium] and you don't say hello to your team-mate, which Nico has always done, that is not good.
"It's not because I am well educated, but it's for the brand Mercedes. This is something I start to worry about now, but it's easy to fix."
However, the Mercedes executive director is confident the team can put Monaco behind them and will spend the time before the Canadian GP encouraging the duo to move on.
"I spoke to the drivers before the race and it is not finished," he said.
"I understand all the comments and I have to wait two or three days, but before it goes to Canada it will be solved.
"I will speak to them like I always do. They always call me when they have problems, so I think it will sort itself out.
"It is normal. I had the same with [Alain] Prost. I hated the guy, but at least I said hello in the morning.
"There are certain limits and these certain limits I can reintroduce because I speak their language, the drivers' language, and they do understand me, they like me and there is no issue."
