Red Bull team principal Christian Horner would be shocked if Mercedes did not develop their car for the rest of the season and believes Toto Wolff is simply playing mind games.
Mercedes have been very open that they don't plan to bring any updates to the coming races to focus on 2022, but Horner is sceptical about that prospect.
"What Mercedes do is very much their business so we just focus on ourselves and Toto loves to throw the throw the line somewhere else," Horner told RacingNews365.com and other select members of the press.
"I cannot believe that they will go through the rest of this year without putting a single component on the car.
"All we can do is focus on on our own job. Of course it's a balancing act between this year and next year but if that means we've all got to work a bit harder then the team is fully up for it."
Horner feels that Max Verstappen's drives across the Styrian GP weekend was their best of the season and he also thinks Sergio Perez put in a great showing too despite finishing fourth.
"It was our strongest, most complete performance so far this year. Pole position here and the win, it's been a great two weeks so far.
"It was a great shame we didn't have Perez up there as well, after a difficult stop, but then his recovery when we converted onto the two-stop was phenomenal."
