Mark Webber believes Mercedes has a big decision to make whether it sticks with Nico R༺osberg and Lewis Hamilton as its driver line-up for 2015.

Hamilton and Rosberg's partnership was strained even further when the two c✨ollided in the Belgian Grand Prix, with Hamilton claiming after the race that Rosberg had admitted he chose not to avoid the incident. Rosberg recently signed a new contract at Mercedes and Hamilton's current deal doesn't expire until the end of 2015, but Webber believes there's a chance the team will have to allow one🦄 of them to leave at the end of the season.

"It's going to be interesting, not just for the rest of the year," Webber told Sport und Talk. 🐓"At the moment it's not a team. Is it OK to have them together in 2015?

"It loꦑoks like the drivers are doing their own thing. Can they drive 🧸together in the future?"

While Webber doesn't believe Red Bull's Daniel Ricciardo has a realistic chance of winning this year's title - saying "Mercedes will really need to implode for Daniel to take the championship" - he does feel neither Hamilton nor Rosberg wilꦕl be wary of an outside challenger.

"Let me tell you, when they get t🍃o the track, they'll only be thinking about each other. There's no-one else really in the race. They are really only🍌 focused on beating each other and that's what happens when you have a car that is so dominant.

"They are going to win the constructors' [title] easy, so the drivers know that the const✱ructors' is done, so all that's lefꦦt is the drivers' championship."
