Baku, July 26, AZERTAC Sky Sports F1's Nico Rosberg says Ferrari need to make "serious changes" after what he perceived as another strategy blunder at the French GP, while he also insists Charles Leclerc is still in the title fight against Max Verstappen despite losing big points after his crash from the lead, according to Sky Sports.It was another dramatic race on Sunday with Verstappen taking advantage of Leclerc's crash to move 63 points clear with 10 races remaining, while Sainz missed out on a podium after a late Ferrari pit-stop call.Rosberg, reflecting on the events, had his say on all those big moments as well as Mercedes' best result of the season in second and third, Lewis Hamilton's upturn in form and more..."I really think it was premature of Leclerc to take the blame."He needs to go back now, because it's really very unusual for that to happen in the way it did, because you're not even pushing to the maximum there, you're saving tyres."For the rear to go like that, one thing could be at that point, that's exactly the point when the wind comes from the rear, and if you get an unlucky gust or something, that can suddenly take 20 per cent of your downforce away right in that moment."And also, what was happening with the engine there? It only takes a little bit of a cut or something that can kick out the rear. I really think they need to take some time to look at that because I still can't believe that it would be a driver mistake."I also found it was a little bit strange, and I think that's where Charles was complaining that he was not able to go on throttle because the car I don't think was even broken?"The front wing was broken probably going into the barriers, but I'm surprised he didn't try and get out of there even more and continue. I'm not sure what happened there."
