Aston Martin Team Principal Mike Krack is confident that Fernando Alonso's podium at Zandvoort is not an isolated event and expects it to return to its earlier season form.
The team has not matched the form from the first part of the season in the second, as it has struggles to match the development rate of rivals Mercedes and Ferrari.
Alonso's second-place podium at the Dutch Grand Prix was the team's best result since the Canadian GP earlier in the season, with the Spaniard often trailing in the final points-paying positions.
When asked about the fluctuations in form, Krack told media, including RacingNews365: "When you look at the season overall, you see teams going up and down all the time.
"To be honest in Zandvoort we also performed better than we expected originally, then you go to Monza and it's obviously a different circuit.
"But it is up and downs we have seen with all the teams so far this year, so that is something that we need to try and understand."

Krack: Never one thing impacting car performance
The Aston Martin has largely shown its strengths at the high downforce circuits throughout the season, with the team having to trade off performance at circuits with other characteristics.
"In Formula 1, it's not never one thing. There are also circuits where there are slower corners, so I think all in all, you always have to try and improve your car," explained Krack.
"Here is a circuit with a lot of high speed corners and then you can also make choices.
"You can choose to go really fast in Sector 1, then you pay a bit of price in Sector 2, or you go for the best possible tyre degradation or you go for speed.
"These are the decisions that you have to make if you do not have a car that is better than everyone else."
