Championship leader Nico Rosberg said he has learned his lessons from events at the controversial Hungarian Grand Prix last month and will change his approach to team strategy decisions at future races.

Rosberg's lead in the championship was trimmed to 11 points at the Hungaroring a month ago when his Mercedes team-mate Lewis Hamilton ignored a team instruction and took third place in a chaotic race.

"I've learnt various things from that race which I will try to adapt to in the future," Rosberg told a news conference on Thursday ahead of this weekend's Belgian Grand Prix.

"I gather it was a bit of a mess (in the media) after Hungary so it's best I don't add too much and not give too many details.

"In general, we discussed it after the race because it's important to review a situation like that.

"I don't want to go into much detail but we sat down and discussed it all, reviewed if we needed to change something for the future and that's what we've done."

Team boss Toto Wolff said: "When it comes to drivers in the same team running alternative strategies, it is usual for them not to make life hard for each other when it comes to overtaking.

"But we must appreciate that we are not in a usual situation anymore."

In the Hungarian race, Hamilton ignored a request to let Rosberg pass him for position during the race and the latter had to settle for fourth place.

Mercedes appear now to have given their duelling title challengers complete freedom to scrap for the world championship.
