Mercedes could be forced to change their driver line-up if the relationship between Lewis Hamilton and Nico Rosberg comes under further strain.
The pair have battled it out for the world championship in the last two years with Hamilton coming out on top both times and the pressure has resulted in their relationship turning sour.
Mercedes has been happy to allow the pair to race against each other but several shunts has cast doubt over the policy, while Hamilton has publically questioned the team's strategy.
Team boss Toto Wolff admits something has to give and has warned the team may have little choice but to change its line-up.
"We took the decision of having two evenly matched drivers in order to make the team progress faster and better," Wolff told motorsport.com.
"It was a very conscious decision three years ago.
"Going forward, we will consider if it is the best set-up for the team. Personality and character within the team is a crucial ingredient for the team success.
"If we feel that it is not aligned with the general consensus, spirit and philosophy within the team, we might consider that when we take a decision, in terms of the driver line-up going forward."
Mercedes have dominated Formula 1 in recent seasons but the driver situation has cast a shadow over their success.
"I feel that the team is stronger than ever. We are having huge unity within the team, but the difficult relationship of the drivers is one of our weaknesses. And that is not good," Wolff added.
"If I were to analyse what are the biggest strengths and the biggest weakness of the team, I would say the biggest strength is the quality and the characters of the personalities within the team.
"The biggest weakness is the dynamic of the relationship between the drivers - and sometimes between the drivers and the team."
