The heat has been turned up at Red Bull after Max Verstappen appeared to ignore team orders in Saudi Arabia.
The Dutchman was asked to keep to a certain lap time and urged not to challenge for the fastest time in the closing stages.
But, he ignored the request to ensure he picked up an extra point against his team-mate.
F1 expert Peter Windsor feels the situation is getting out of control with Verstappen likely to blank team requests in the future.
He said: “It was very clear that, given the slightest opportunity, Verstappen would have pushed Perez all the way to the finish.
“This needs to be looked at. How they’re going to do it? I have no idea, because Verstappen is not the kind of driver to listen to anything other than ‘go and win the race’.”
