Aston Martin Team Principal Mike Krack has assessed the team's chances of returning to being the second quickest car behind Red Bull.
Fernando Alonso has achieved six podiums so far with the team out of 12 races, while Lance Stroll has come back from a pre-season injury and regularly finished in the points.
The team has brought significant updates to the AMR23 in the tight development battle with Ferrari, Mercedes and McLaren, but they have not produced the performance they expected with their form lapsing in recent races.
This has resulted in them dropping behind Mercedes in the Constructors' Championship, while Fernando Alonso's third place in the Drivers' Championship becomes increasingly under threat by Lewis Hamilton.

When asked if he agreed with Alonso's assessment that they are now no longer the second quickest car, Krack told media including RacingNews365: "Yes"
Krack believes this car development war will impact their ability to return to second quickest.
"Under normal circumstances, you would say to gain three positions in such a field, over the short time of 11 events, it’s very hard and very ambitious.
"On the other hand, the gaps are very small. We have seen how much we have lost, and I think the most important is to recover that and try to recover a little bit more."
