Ferrari driver Carlos Sainz has been penalised for excessive engine usage, meaning he will start the French Grand Prix from the back of the grid.

Sainz sits in fourth place in the drivers' championship, and finished the final practice in second place. 

However, he will now start Sunday's race from the back after Ferrari took their fourth new engine of the season, one more than is permitted.

This penalty has been added on to the 10-place sanction that he had been given for the new electronics control unit that Ferrari opted for on Friday.

He will be joined at the back of the grid by Kevin Magnussen of Haas, who was penalised for changing power unit components.

Red Bull's Max Verstappen was fastest in the final practice, with the reigning champion clear of Sainz's Ferrari team-mate Charles Leclerc, who finished third quickest.
