Carlos Sainz Jr. says he is sure his string of bad luck will come to an end, as he was forced into retirement for the fourth successive race in Belgium.
Sainz was set to start from 10th position at Spa-Francorchamps but a loose connector in the engine led to a loss of power on the formation lap and he had to return to the pits.
Sainz rejoined the action two laps down and ultimately returned to the pits in order to preserve the engine in his Toro Rosso.
"It was a frustrating way to end what was being a good weekend," he said.
"During the formation lap I felt I had no power, so I had to box. Luckily they managed to solve the issue and I was able to go out and race, but being two laps down there wasn’t much I could fight for, just hope for rain and be lucky.
"After two stints though, we decided to retire to save engine mileage. I’m obviously very disappointed and desperate to finish a race, as it’s now been four consecutive races where I’ve had to retire while fighting for points.
"But this isn’t going to bring me down. I’m going to keep pushing and show my good performances whenever I can, like I did in qualifying for example.
"We know that this world is sometimes like this and I’m sure this unlucky streak will come to an end soon – hopefully in Monza!"
