Red Bull boss Christian Horner doesn't believe Mercedes will follow his team's track record of swapping drivers midway through the season.
George Russell has been heavily linked with a move to the Silver Arrows at season's end, however reports emerged on Tuesday suggesting he could be brought in to replace Valtteri Bottas during the current campaign.
Horner, who hasn't been afraid to swap Red Bull drivers in the past, doesn't think Mercedes will adopt a similar approach.
“Valtteri has demonstrated he can drive the car very quickly," Horner told the PA news agency. "Circumstances are always going to happen so let’s see how things pan out, but Valtteri has done a great job for Mercedes over the last few years.
“I would be surprised if they did switch Valtteri and George around mid-season.”
Mercedes currently sit 18 points up on Red Bull in the constructors' championship following the Portuguese Grand Prix, which saw Lewis Hamilton claim his 97th career victory ahead of Max Verstappen and Bottas.
