Sebastian Vettel's retirement announcement sent shockwaves around the paddock, especially among fans who hoped for the Quadruple World Champion to continue in the sport.
Vettel made clear he would need to see development from Aston Martin to be convinced to sign an extension, whilst Mike Krack also admitted the team still needed to show the potential of their project.
Both parties emphasised the importance of the rounds before the summer break, and as Sebastian's father Norbert told RTL, one of these races was difficult for the 35-year-old to come to terms with:
"It's a shame, but I understand him. That was an incredible career for my son, and the low point was Austria.
"It hurt him so much to drive around at the back of the field, and that accelerated his thought."
After introducing their massive upgrade package for the Spanish GP, there was optimism that Aston Martin could show the kind of performance that would incentivise a World Champion to continue racing.
Regrettably, with the exception of the Baku GP, the Silverstone-based team's pace has been quite mediocre, ultimately insufficient in keeping Vettel at the team for longer than two seasons.
