Wednesday morning's Formula 1 news roundup:

Black suit not reason for hot Bottas - Wolff

Toto Wolff has played down Valtteri Bottas' comments about his black racing suit for 2020.

As the Finn admitted in Barcelona that his championship hopes are "drifting away", he complained that he lost 3kg during the Spanish GP because his overalls are "f*****g hot".

Mercedes switched its car livery and driver suits to black for 2020 in deference to Lewis Hamilton's support for the Black Lives Matter movement.

But team boss Wolff denied that the colour change is Bottas' problem.

"We just have a new material," he told motorsport-total.com.

"Maybe we have to look again to see if we can find a compromise on how we can get it a little thinner."

Indeed, Bottas confirmed that more than just the racing suit's colour has changed for this season.

"There's a new homologation this year for the overalls, so they are thicker, and the underwear is thicker, so I don't know how much effect that has," he said.

Ex-Red Bull driver says Albon has 'lost his way'

Alex Albon has "lost his way" at Red Bull, according to former team driver Robert Doornbos.

While the team is for now standing behind the struggling British-born Thai driver, it is clear that his shoulders have slumped in recent races.

"It's really tough for him," Doornbos, who briefly raced for the energy drink owned team's premier team in 2006, told Ziggo Sport.

"Albon has really lost his way. He's broken there," he said.

"I really hate that so many people have bad words for him because he's a really good racing driver," said Doornbos.

"But this is also just motorsport. If you get lost, it can take a long time to find your way again."

Another former F1 driver, JJ Lehto, thinks it is possible that Red Bull will sign its former quadruple world champion Sebastian Vettel to replace Albon.

"Red Bull is certainly considering all options on how to make the team more competitive," he told Iltalehti.

"Max Verstappen makes it so hard for those who drive alongside him. Albon and Pierre Gasly are familiar options for them, but so is Vettel.

"The team knows what he can do when he's at his best."

Lehto said Vettel may also regard returning to Red Bull as his best option for 2021, as rumours swirl that the German may in fact not go to Aston Martin.

"Vettel will definitely be wondering what that team will be able to do next year," he said.

"Aston Martin is a car brand, yes, and it brings a certain value to the team - but what are they actually capable of?" Lehto wondered.
