Ralf Schumacher thinks Aston Martin are “embarrassing” themselves with their current performance – and unlikely to improve much this season.

Aston Martin, by their own admission, were badly affected by the tweaks to the aerodynamic regulations for this year which impacted on they and Mercedes the most.

As a result, they are isolated in seventh in the Constructors’ standings, although they would be much closer to sixth-placed AlphaTauri had Sebastian Vettel not been disqualified from the Hungarian Grand Prix due to a fuel sample issue.

There was another tricky moment for Vettel during the Turkish Grand Prix last time out when his experiment to try slick tyres failed completely, costing the four-time former World Champion any chance of scoring points along with his ninth-placed team-mate, Lance Stroll.
