Aston Martin would be ‘foolish’ not to try and retain ‘very competitive’ Vettel, says Team Principal Krack

Aston Martin Team Principal Mike Krack has said his squad would be “foolish” not to try and keep Sebastian Vettel beyond the end of this season, when the four-time champion’s current contract expires. But Krack also admitted that Vettel would need to see “progress” from the squad in order to want to extend his stay with the team in green.
