Max Verstappen delivered one of the best radio messages during Friday’s second practice in Brazil, but it was anything but a laughing matter as the Red Bull driver again suffered from downshift issues.

The Dutchman was third quickest in both of Friday’s sessions but brought his day to an early end, returning to the pits with six minutes remaining in FP2.
