Max Verstappen's costly crash in Monaco was caused by his impatience, according to Red Bull motorsport chief Helmut Marko.
Verstappen ruined his weekend in the closing stages of the final practice session, hitting the wall at the Swimming Pool chicane and damaging his car. He missed qualifying as a result and was forced to watch on from the Red Bull garage as teammate Daniel Ricciardo claimed a comfortable pole position.
After the crash, TV cameras caught Verstappen in animated conversation with Marko, the notoriously ruthless head of Red Bull's driver programme. Verstappen has been involved in a series of spins, collisions and crashes this year; the most recent prompted team boss Christian Horner to say the Dutchman must learn from his mistakes stop making errors.
