Piastri fills a spot within the 2023 F1 driver line-up after signing for McLaren alongside Lando Norris.
The Australian was in the course of a tug-of-war between Alpine and McLaren with the Woking outfit finally popping out on prime after a verdict was reached by the contract recognition board.
Piastri has loved an unimaginable rise to F1, profitable the Method Renault Eurocup, F3 and F2 titles in consecutive seasons.
Talking on F1’s newest episode of the Past the Grid podcast, Horner commented on Piastri’s state of affairs and the way he had the chance to signal him a number of years in the past.
“He drove for the Arden staff in Method 4 and Method Renault, and was clearly a major expertise,” Horner stated.
“There was a chance for Pink Bull to have a look at him on the time, and we didn’t take up that choice, which is one thing that I remorse. However what he went on to realize is phenomenal, in Method 3 and Method 2.
“Now if he’d have been a driver right here, there isn’t a manner that he wouldn’t have been below lock and key for a interval in time. As I say, I wasn’t social gathering, it’s tough to evaluate what was promised or reneged on or so on. However actually, it was surprising, most likely from a number of areas.”
Pink Bull have promoted a wealth of expertise to F1 by means of its sister staff AlphaTauri (previously Toro Rosso) with the likes of Sebastian Vettel, Max Verstappen and Daniel Ricciardo coming by means of the ranks.
The expertise appears to have dried up with Pink Bull trying probably elsewhere for the 2023 F1 season as they look for a alternative for Pierre Gasly, who’s eager on a transfer to Alpine.
Colton Herta was being thought of however on account of points surrounding him getting a superlicence, that’s unlikely to occur.
Nyck de Vries is a possible choice for AlphaTauri, notably after it was revealed that the Dutchman met Pink Bull guide Helmut Marko final week.
Whereas loads of Pink Bull’s F2 junior drivers have underwhelmed, Horner stated that he’s been impressed by Japanese driver Ayumu Iwasa in F2 and Isack Hadjar in F3.
“We’re persevering with to put money into youth, we’ve acquired some nice children within the programme, all the best way from karting and entering into Method 4 now, upwards,” Horner added. “I feel it’s one thing Pink Bull has accomplished so nicely, giving these children an opportunity, investing in younger expertise, and giving alternatives they in any other case wouldn’t have had.
“Isack Hadjar in Method 3 this yr has had an awesome debut season. I feel [Ayumu] Iwasa in Method 2 has been a standout driver for me. They’re simply two of the fellows on the programme.
“Liam Lawson has had a tricky yr, however he’s once more one other expertise. Dennis Hauger has been a bit underwhelming in Method 2 after such a dominant yr in Method 3. However once more, how a lot of that’s him and the way a lot of it’s gear?”
