Former Red Bull driver Mark Webber believes Mercedes no longer has drivers competing with a common goal, with Nico Rosberg and Lewis Hamilton battling individual glory.
Although Mercedes lead the Constructors' Championship by 150 points from Red Bull with just seven races remaining the season, there are only 29 points between Rosberg and Hamilton in the Drivers' Championship standings.
While several controversial moments earlier in the season highlighted the fact that Rosberg and Hamilton don't necessarily see eye to eye, the rivalry within Mercedes seemed to reach its zenith when Rosberg clipped Hamilton's left rear on the second lap of the Belgium Grand Prix last week while the pair were battling for first place.
As a result to the damage to his car, Hamilton was forced into eventual retirement, while Rosberg recovered from the broken nose his car suffered to finish in second place.
"Now we have a very difficult situation at Mercedes where the drivers are not enjoying a good relationship," Webber toldRed Bull show Sport und Talk.
"It's going to be interesting, not just for the rest of this year but can they drive together in the future? Is it OK for 2015 for the team to have the two together?
"The thing is, who is going to try to put this back together? Is it the people who pay Niki [Lauda] and Toto [Wolff's] wages? At the end of the day, if the drivers are not listening to these guys, do they have to say, 'Lewis and Nico, you go chat to the big guys at Mercedes, as they're paying you to get the job done in a team environment'.
"At the moment it's not a team, it looks like the drivers are doing their own thing.
"Let me tell you, when they get to the track, they'll only be thinking about each other.
"They are really only focused on beating each other, and that's what happens when you have a car that is so dominant.
"The drivers know that the Constructors' is done, so all that's left is the Drivers' championship."
