Oscar Piastri was not accepted into the Red Bull Driver Academy, which Christian Horner regrets.

Oscar Piastri's inclusion in Red Bull's driver academy is something Christian Horner wishes he had done years ago.

After a protracted contract dispute with Alpine this summer, Piastri will compete for McLaren in 2023. Piastri progressed through the French company's driver academy in previous years before winning the Formula 2 title last year.

Red Bull, according to Horner, would never have let the highly regarded Piastri escape its grasp the way Alpine did.

In reference to the team he and his brother started in 1997, Horner said of the driver on the Beyond the Grid Podcast, "He drove for the Arden team in Formula 4 and Formula Renault, and had obviously a great talent.

"Red Bull had the chance to look at him at the time, and we passed on the chance, which is something I regret. But what he went on to accomplish in Formula 3 and Formula 2 is incredible.

"Now there is no way that he wouldn't have been kept under lock and key for a while if he had been a driver here. Because I wasn't involved, it's challenging for me to assess what was promised or broken at Alpine.

However, it was unanticipated and likely came from numerous sources.

In the upcoming season, Piastri will take Daniel Ricciardo's spot at McLaren, another Australian.

While Alpine has not yet filled the position Piastri declined to take, Ricciardo has not yet said what his future move would be. Red Bull and Alpine are reportedly in negotiations for Pierre Gasly, a current AlphaTauri player. However, this deal is predicated on Red Bull's ability to replace Gasly with Nyck de Vries.

Colton Herta, an IndyCar driver, was once under consideration by AlphaTauri, but the American has not received the superlicence exemption he would have needed to compete in Formula 1.
