Nico Rosberg is firmly of the belief his bitter intra-team feud with Lewis Hamilton will soon be forgotten.

Rosberg and Hamilton finished Sunday's Monaco Grand Prix as the best of enemies following what proved to be a contentious weekend for the Mercedes duo.

Hamilton was left enraged by what he saw as Rosberg's deliberate bid to thwart his final qualifying lap, with the latter's subsequent win from pole position only adding to the ire of the Briton who was forced to settle for the runner-up spot.

The podium ceremony proved to be a tense affair as they ignored one another, leaving Mercedes non-executive chairman Niki Lauda to state they should start behaving like "grown-up sportsmen".

Rosberg concedes the current situation is a frosty one, but has no doubt it will be resolved.

On a visit to watch Germany's World Cup squad in action at a training camp in Italy, Rosberg told a news conference: "We discuss the issues and we have already discussed them.

"It will again be better and it will be forgotten.

"In our sport we can only have success as a team. Nothing can happen alone. I make an effort for teamwork and the atmosphere in the team.

"It is a bit more difficult internally at the moment, but it has happened in the past in our sport."

Rosberg's victory around the streets of the principality resulted in him regaining the lead in the drivers' championship by four points from Hamilton.

With the pair comfortably ahead of any of their rivals, they are set to continue to go toe-to-toe for the remainder of the season.

McLaren racing director Eric Boullier believes it will be impossible for Mercedes to maintain any unity between them over the remainder of the campaign.

Boullier, who has experience as a driver manager with Gravity Sports Management, feels Mercedes motorsport boss Toto Wolff has his work cut out to keep a lid on the situation.

"It's impossible at this early stage of the season, so good luck," said Boullier.

"It's going to be tough for them to go through the rest of the season."

Naturally, there is no envy from Boullier with regard to Wolff's position, adding: "Yeah, it's difficult for him. As I said, good luck.

"Better to have his cars, not his job!"
