Nico Rosberg believes there will be "fireworks" between Charles Leclerc, Sebastian Vettel and the Ferrari hierarchy after the Singapore Grand Prix, but credited the Monegasque drivers' reserved reaction after losing out on the win of the race.
Leclerc secured pole for the third race in succession, but missed out on victory at the Marina Bay Circuit when Vettel undercut both him and Lewis Hamilton to move from third to first.
Although Ferrari considered resetting the order of their drivers, Vettel was ultimately allowed to take the win, with Leclerc following him home in second to secure the Scuderia's first 1-2 finish since Hungary 2017.
Leclerc demanded answers from Ferrari during the race and confirmed he would seek an explanation after it, with Rosberg suggesting those talks may be feisty.
"Leclerc after the race I think he was quite smart because it's a fine line," Rosberg said on his YouTube channel.
"One is to go full on in public, complain, which is not the right way to do it, I myself have experienced some of those situations where it's just a mistake.
"To go too strong in public is wrong, but to do nothing in public is also wrong because you do need to set a tone and not make it too easy for your team to walk all over you as a driver, so I think he found the balance right there.
"He questioned it a lot in the race, then after the race he didn't speak about it at all and just congratulated and was very happy for the team to finish 1-2 which is most important.
"But internally there's going to be fireworks."
