Both of these guys are rally drivers for years. I remember Valentino Rossi when he drove WRC Rally Great Britain with Peugeot 206 WRC some twenty years ago. His co-driver was Carlo Cassina, ex-Liattti's co-driver. They were out of the rally very soon because Rossi was too fast for one corner and rally is not a circuit racing.
What about Kubica?
Ex-Formula 1 driver and also a winner who had a terrible accident in 2011 when driving Škoda Fabia S2000 on some small Italian event.
He later drove in the World Rally Championship with M-Sport Ford and in the lower category with Citroen where he won that class overall that season.
So, they are both great circuit drivers and we are talking about Rally Monza which is held every year at Monza circuit. So why not?!
They coul be very good there with possible top ten finishes.
