More Mercedes wins unlikely for now - Rosberg

Nico Rosberg has played down his chances of adding another pole or victory to his 2012 tally this weekend in Belgium.

Since breaking through in China early this season, the German has only managed one more front row start and one more podium, and he was tenth at the finish last time out in Hungary.

"At the last race we had balance problems in the long corners," Rosberg is quoted as saying at Spa Francorchamps by Germany’s Speed Week, "and here there are a lot of the same type of corners.

"I believe we can have a good weekend, but whether it’s enough for a very good result, I don’t know," the 27-year-old insisted.

"I believe that in Monza and Singapore we will have a better chance to have a good result, but I don’t know if it’s realistic to talk about winning," Rosberg added.
