Bagnaia probably, Ducati is in a so good shape right now...
It will make interesting the end of the season, if I'm not mistaken there is 50 points in advantage for Quartararo and 4 races left...
Ducati and Bagnaia are very strong at the moment, 50 points is a good cushion but it can be gone quickly. If both of them drop out, the world championship would probably be decided prematurely. Fabio could digest one well, but if Bagnaia dropped out, the lead would already be too big.
