Perez could miss out on Sochi upgrade after Stroll crash

If Racing Point does not have enough spares for both its drivers, then Sergio Perez will have to wait as Lance Stroll is ahead in the championship and takes precedence.

Sergio Perez, who is leaving Racing Point at the end of the year, said on Sunday that he was looking forward to having the upgrade in Sochi.

Racing Point will have its work cut out to get an upgrade onto Sergio Perez's car in Russia next week after Lance Stroll crashed in Sunday's Tuscan Grand Prix.

Stroll's RP20 car was the only one with the new package at the Italian circuit but the Formula One team had hoped to provide the same parts to Mexican Perez in Sochi.

“He (Stroll) did have the upgrade so now we're going to have to do a lot of work to get enough parts together for both of them to have the upgrade in Russia,” said team principal Otmar Szafnauer.

The team owned by Stroll's father had only enough spares to run one car with the upgrade in Mugello.

If it does not have enough for both, then the Mexican -- who is leaving at the end of the year to make way for Sebastian Vettel - will have to wait. Stroll is ahead in the championship and takes precedence.

Enough spares are needed because the car cannot just revert back to the old specification if something is damaged.

Perez had told reporters before Sunday's race, where he finished fifth, that he was looking forward to having the upgrade in Sochi.
