McLaren driver Oscar Piastri has conceded blame for the incident that took both himself and Ferrari's Carlos Sainz out of the Belgian Grand Prix lay with both parties.
The Australian rookie had secured his best result in F1 with second in the Sprint on Saturday but failed to finish the first lap at Spa-Francorchamps on Sunday after contact at Turn 1.
Piastri made a good start and made his way up the inside of Sainz into La Source but the space was closed as the Spaniard locked up and turned in to avoid Lewis Hamilton's Mercedes.
The MCL60 was shoved into the inside wall, damaging the steering to leave Piastri unable to return to the pits, whilst Sainz's right-hand sidepod was punctured, eventually sending him into retirement with the Ferrari showing no performance in last place.

Reviewing the incident with media including RacingNews365, Piastri said: "It is quite firmly in the category of a lap one, Turn 1 incident.
"I got a good start and got my nose alongside. When we got to the inside, Carlos moved to the right and locked up, I also had to try and avoid that a bit.
"From there to the apex, my options were quite limited. I will look back over it more and see if there is more that I could have done."
"Looking back on it, we both could have done things differently.
"It is a very tight Turn 1. Carlos didn't have many options from where Lewis was either."
