Isola can not say anything about the crash of Verstappen and Stroll. According to him, it's too early and the tyres need to be analysed first to find out what caused the crash. The Italian is willing to make the first guess.
He thinks that debris on the asphalt was the cause because the left rear tyres are not subjected to the most pressure in the race at the
Baku City Circuit. On top of that, the punctures happened at about the same spot on the track. But: Pirelli is going to investigate first and then will come with a statement.
