Red Bull Team Principal Christian Horner believes McLaren has now become the most "consistent" rival to the team in Formula 1.
Earlier in the season Aston Martin and Fernando Alonso was the only team to finish on the podium consistently, with the Spaniard now on seven podiums so far this year after the Dutch Grand Prix.
But since introducing their updated specification car at Austria, Lando Norris has become the second-largest points scorer and is close to Alonso's podiums.
Horner believes their resurgence in form has led to McLaren becoming the most consistent rival to Red Bull.
He told media, including RacingNews365: "It's moved around over the last four or five races but they've become certainly more consistent, the most consistent challenger.
"They're doing a good job and the drivers are driving well. Particularly Oscar, in his rookie season is doing a very strong job."

Verstappen: McLaren has best driver lineup
Max Verstappen believes McLaren's strong driver lineup is enabling them to be consistently behind Red Bull as a rival on track.
"As a team they are probably the most consistent, compared to the others behind us," said the three-time World Champion.
"I do think they have the best driver line-up out of all of them. They are operating really well.
"It's going to be interesting to the end of the year, but also I think [about] the start of next year to see where everyone is at."
