I dont know ! They must definitely be doing something wrong !

Throwing so much money at their team and then this kind of pessimism even before the first race. And after today^s Practise, it doesn't even look like they are downplaying their chances

Maybe they should start by getting some good drivers. Or at least get some drivers with a positive attitude !
