THing with Rosberg is he's complaining or saying nothing interesting, he has almost no personality. When he tries to be funny he isn't. Kimi doesn't say much but he still shows a distinct personality, makes jokes. He's supposedly great off camera just not comfortable on it. Rosberg speaks plenty he just has nothing to say.
Even Mika was funnier and showed more personality than Rosberg. He's also a dull as dishwater driver, can barely overtake, isn't aggressive, doesn't even try. LIke in China he didn't try to pass Hamilton, complained he was too slow and after the races said his tires would have been destroyed if he tried. A race later and Hamilton spent 15 laps tucked up under Vettel's wing, no tire destruction at a track with worse tire deg. He tried, Rosberg didn't. Outside of decent one lap pace Rosberg is a poor driver in a currently great car.
EDIT:- Interview with Alonso will be interesting today, "so do you regret leaving Ferrari", "no I don't want to fight for second places, only time they win is when Mercedes screw up", "errrm......." .
I don't think Alonso would drive for anyone for free, I think the move to Mclaren was entirely about money, initially trying to get more out of Ferrari, Ferrari not really loving his attitude already, moving to nab Vettel and leaving Alonso with no choice but Mclaren. Fact is a LOT of the reasons Ferrari are fast today were put in place long before Alonso moved. The ex Merc ERS car, the Merc fuel guy, a couple of other key guys, the change in direction of the engine, Allison, another Lotus guy, the Haas deal and the aero cheating thing they are doing. Ferrari looked to have made all the right moves and right decisions, sure they may not have paid off but the clear changes were obvious. Same way Merc had made the right changes and Mclaren looked to have made all the wrong ones. New chassis, new engine, rushed engine, new collaboration, that was never a short term fix but a short term disaster.
