Lando Norris was particularly harsh on himself following the British Grand Prix, feeling McLaren had once again thrown away a race victory.
The critical call for Norris centered around the switch back from intermediate to slick tyres and the compound of rubber he fitted.
Second-placed Lewis Hamilton fitted soft tyres with third-placed Max Verstappen opting for the hards, with the duo stopping on lap 39 as Norris continued for a further tour of Silverstone.
Norris did have a fresh set of medium tyres available, but did not fit them, opting for a set of used softs and was leap-frogged by Hamilton, who went onto win.
Norris was passed late on by Verstappen for second as the softs degraded, with McLaren boss Andrea Stella feeling the team needed to take responsibility for the call.
On the sister car of Oscar Piastri, McLaren did fit the new mediums it had saved for just this situation, with the Australian closing a 15-second gap to Norris to just five seconds by the flag with a flurry of fastest laps, although Carlos Sainz nicked the bonus point on the final lap.
The radio traffic between Norris and his engineer Will Joseph and Piastri and Tom Stallard is available to read below - and tells the story of two different approaches.
