Red Bull boss Christian Horner says Pierre Gasly was like a "different driver" in Formula 1's British Grand Prix.
Gasly had been the subject of speculation over his F1 future after a difficult start to his first season with Red Bull and entered the British GP having scored 43 points compared to team-mate Max Verstappen's haul of 126.
The former Toro Rosso driver was a lapped seventh in Austria ahead of the British race and led to a rethink at Red Bull to help Gasly recover, including a switch to Verstappen's set-up.
Horner said Gasly, who finished fourth at Silverstone, has made a step forward.
"I think Pierre has done a very good job all weekend," said the Red Bull boss.
"Turning the page from Austria, that was a really tough weekend for him, and coming here [he was] just focusing on what he is doing and not worrying what his team-mate was doing.
"Just getting back to basics, he has been like a different driver all weekend.
"From the first session [at Silverstone], he has been competitive. He has built on that in FP2, and in all three elements of qualifying, he was competitive and the race again here.
"He passed [Sebastian] Vettel in the race and was racing hard with [Charles] Leclerc and I thought he drove very well."
Asked by Autosport if the Gasly turnaround was simply down to a new set-up, Horner said: "Not really.
"I think that just his approach to the weekend has definitely helped and he has just turned up here and been competitive."
Gasly said the British GP had felt like a "massive" step forward for him, but that he was disappointed to miss out on a podium finish.
"I think it was by far the best weekend of the year, we can be pleased," Gasly said.
"There were quite a lot of things going on after Austria, a lot of meetings with the team checking how we can improve the whole thing.
"We made a few changes and [I'm] just pleased that from the first session we could see a big step forward.
"It was a strong Friday, strong Saturday, strong Sunday. I just enjoyed the whole weekend a lot more so I think we can be pleased with the step we made.
"I am so pleased with the fourth place but, of course, as a competitive guy, I am a bit disappointed to miss out on the podium by a couple of seconds.
"I'm a bit gutted now but I think we need to look at the whole picture and the whole weekend and it was a big step forward."
