Alpine team chief Otmar Szafnauer on Friday accused the team's reserve driver Oscar Piastri of lacking "integrity" as a row over his future continued to dominate paddock gossip at the Belgian Grand Prix.
Piastri, a 21-year-old Australian who has won the Formula Three and Two titles in successive seasons en route to a F1 career, is at the centre of a contract dispute involving Alpine as he seeks to break free.
Alpine claim that Piastri, managed by compatriot and former F1 driver Mark Webber, signed a contract with them for 2023, which he has rejected as he bids to move elsewhere.
He is heavily linked with a switch to McLaren to replace fellow-Australian Daniel Ricciardo, who on Wednesday announced he had agreed to leave the team at the end of this season. "My wish for Oscar was that he had a bit more integrity," Szafnauer said. "He signed a bit of paper back in November and we've done everything on our end of the bargain to prepare him for F1 and his end of that was to either drive for us or take a seat where we would place him for the next three years." The dispute began in the wake of Aston Martin's recruitment of two-time champion Fernando Alonso from Alpine to succeed retirement-bound four-time champion Sebastian Vettel next season.
