Former Formula 1 driver Mark Webber is doubtful that Lewis Hamilton and Nico Rosberg can remain as teammates.

The Mercedes duo are said to be at loggerheads after colliding in last weekend's Belgian Grand Prix.

"At the moment it's not a team," Webber, who himself had a feud with Sebastian Vettel, is quoted as saying by BBC Sport. "Is it okay to have them together in 2015? It looks like the drivers are doing their own thing. Can they drive together in the future?

"The thing is, who is now going to try to put this back together? Is it the people who pay Niki's and Toto's wages? Because 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, because they're paying you guys to get the job done in a team environment'?"

The FIA confirmed earlier this week that no action will be taken following the coming together at the Spa-Francorchamps.
