Toto: "For me and for the team, this is the most painful day of the last six years - to lose a possible 1-2 finish in this way, through our own mistakes and unreliability, just hurts so much.
"We had a spectacular first lap: a great getaway for Lewis and Valtteri battling back into P2 under braking for Turn 4. For the first 13 laps, it looked good, with both drivers in control and managing the pace well.
"The first blow was Valtteri's retirement after losing hydraulic pressure - this brought out the VSC. We decided to leave Lewis on track for one lap, because we thought it would take longer to clear the car from its position, and be able to react what the cars behind us did on the following lap.
"But the VSC cleared sooner than predicted; we simply made the wrong decision. That left Lewis with an uphill battle - we pitted soon after racing resumed, put him on the soft tyre, and he then had to try and make up the ground on track. In doing so, the rear tyres blistered, he lost position to Sebastian, then we decided to pit again as there was nothing to lose from doing so - but, shortly after, a loss of fuel pressure forced him to retire.
"A double retirement through reliability is hard to stomach but we know from bitter experience that the difficult days are when we learn the most. We will pick ourselves up in the next days, learn from our errors and go to Silverstone with our heads held high.
"It is a home race for the many team members in Brackley and Brixworth; we will be aiming to come back strong and make amends for our failures today."
