Ferrari have the capability to threaten Red Bull's recent dominance in Formula One, so says 1978 champion Mario Andretti.

Red Bull secured their second successive constructors' championship last month, with their number one driver Max Verstappen cruising to his third successive title at the Qatar Grand Prix shortly after.

Despite the poor form of Verstappen's team-mate Sergio Perez's, Red Bull have still accrued more than double the amount of points of the second-place team, Mercedes.

However, tentative signs in recent weeks have begun to hint at a long-awaited shift away from Red Bull’s dominance.

In Singapore, both Verstappen and Perez struggled - finishing fifth and eighth respectively - as Ferrari's Carlos Sainz claimed victory.

Ferrari were tipped to be serious title challengers this year and, despite their poor start to the season, Andretti is encouraged by their performances as of late.

"Well, they've shown the capability," he told Stats Perform. "There were two successive races where they were on pole, and then the one where Max Verstappen had some issues which they won.

"So, they're there and can cause some issues for Red Bull. You're seeing Ferrari and McLaren also annoying Red Bull quite a bit. And that's the interesting part as well."

McLaren have been the surprise package in the second half of the F1 season, having struggled with their car earlier in the year.

The British team have bounced back superbly, with Lando Norris and Oscar Piastri both finishing on the podium in back-to-back races in Japan and Qatar and Andretti believes the future is bright for the young duo.

"It's been really interesting to watch how much McLaren has really improved in every way," he said.

"Obviously, they've given their drivers the equipment and the improvements that they needed to be competitive.

"They've been right there, annoying the very top and Red Bull quite a bit. Two young drivers, one being a total rookie. There's a future there and no question, something to be built on.

"Lando has shown that he is capable and between the two of them, it seems like they really get along very well. There seems to be a lot of harmony within the team."

McLaren's rapid rise has seen them put daylight between themselves and rivals Alpine this season.

Alpine pipped the British team to fourth in the team standings last season but have endured a disappointing season in 2023, with drivers Esteban Ocon and Pierre Gasly only able to secure one podium each so far this year.

They sit sixth in the standings and a considerable 129 points behind McLaren with six races remaining, but Andretti believes the team will soon rediscover their winning formula.

"You never know why some teams all of a sudden they fall behind; there are many reasons for that," he said.

"I wish you could say 'do this and that, and you'll be right back where you were, or even better', but there's always a reason somewhere.

"That's nothing unusual in this sport. And sometimes the team just have to reboot, but their competitive capability is there. No question. They've shown that before."
