Without a doubt he can. This man has a sparkle back in his eyes and a care for his car because he knows he can deliver. BUT Merc need to fix that tire deg. And Michael needs to find a bit more pace (0.1s or 0.2s) in Qualifying, which he can do. This is a legend who has underperformed the past two seasons (save for Spa and Canada last year) and knows this year he can do better. And you can see he wants to. I predict a podium (3rd) for him next race, and we'll see from there. I may just say China could be Schumachers 92nd win, but the next race will let me analyse the Merc more. I can that if that Merc performs, Michael will win in China, Britain, Canada and Belgium. Rosberg should also win a couple (German?). But McLaren are very strong...
In short: Yes he can, and if he believes that, he will.
