Red Bull team boss Christian Horner has apologised to Daniel Ricciardo after his driver's retirement at the Mexican Grand Prix was traced to a clutch issue on Sunday night.
Ricciardo was running in a strong second place behind Red Bull teammate Max Verstappen and fending off Ferrari's Sebastian Vettel when his car broke down with ten laps remaining. His retirement in Mexico is the latest in a long list of mechanical failures this year and means he has failed to make the chequered flag on eight occasions in 2018.
Horner took to Instagram to apologise to Ricciardo after the race.
