Nico Rosberg has conceded to keeping some secrets to himself in his Formula One title fight with Mercedes team-mate Lewis Hamilton.

Mercedes motorsport boss Toto Wolff revealed following Rosberg's win in Austria on Sunday, with Hamilton runner-up, that transparency was "suffering a little bit".
Wolff again called on both of his drivers to have "a transparent and open way of working with each other" to guarantee Mercedes' current level of dominance, not just for this season, but for the future.
Rosberg admits all data between himself and Hamilton is shared, but in a championship scrap between two team-mates, the discovery of any advantage here or there has to remain undisclosed.
"It's all open - the data, everything, is open," said Rosberg.
"It's just that sometimes you are not going to put it on the table, and say 'look here at what I've done'.
"If I find a little bit of an advantage somewhere then I'm not going to tell everybody about it. I'll keep it to myself.
"But in the background we're racing for the Silver Arrows. Everything is free because the team need to be strong, and we're strongest when we work together, and we do work together.
"But at the same time we're fighting each other, so whenever we can have a little bit of an advantage over the other then we'll take it."
In finishing ahead of Hamilton in qualifying and also in the grand prix in the last three races to extend his lead to 29 points, the German - who turns 29 on Friday - is revelling in the psychological damage he is causing the Briton at present.
"It's good to know I have the momentum fully on my side, definitely good, and I need to prolong it as much as possible," added Rosberg.
"There will inevitably come a point where Lewis will pull it towards him again, so I need to make the most of it for now.
"I need to try to keep it as long as possible and keep going because I'm on a good run at the moment.
"It helps my confidence to have the recent results behind me - the qualifying results, race results. It's always better than being a little bit on the backfoot."
With the next race on Hamilton's home soil of Silverstone, another Rosberg triumph in the British Grand Prix on July 6 could prove thoroughly demoralising for the 29-year-old.
Playing down the significance, Rosberg said: "For me it's a race like any other.
"It's a home race for the team, which makes it all the more important, and I'd love to do a one-two there - and the same order as in Austria - that would be great.
"It's the best gift we could give everybody, so we'll try and do that, that would be awesome.
"But it wouldn't be more special for me if I manage to beat Lewis at Silverstone. I don't think about it that way.
"But to win at Hockenheim (the German Grand Prix that follows on July 20), now that would be amazing, just as it was when I won in Monaco - very special."
