Sauber driver Marcus Ericsson has blamed “overheating brakes and cold tyres” for his crash behind the safety car during the Monaco Grand Prix.
The Swede was running 16th when the safety car was deployed for an incident involving his team-mate Pascal Wehrlein and Jenson Button at Portier.
He was struggling with overheating brakes and cold tyres during the slow-speed running and after four laps behind the safety car, he crashed out of the race.
Ericsson was un-lapping himself when he slid off track going around the first corner and hit the barrier, bringing his race to an early end.
“It has been a very tough weekend from the start to the end,” he explained after retiring from the Monaco GP.
“With the pace we have had this weekend, the race was decent from my side. Unfortunately, I then had some issues with the brakes overheating behind the safety car.
“I tried to bring the brake temperature down, but at the same time I had to keep the tyres in the right working window.
“The combination of overheating brakes and cold tyres made me struggle a lot to stop the car, so I could not avoid sliding into the barriers.”
