Apparently Bernard Ecclestone was talking to Auto Motor un Sport and suggested that organisers would clean the track surface before race on sunday to get rid of the rubber stuck on the racing line.

He also would like to se harder tyre compounds.

The gist of these changes would be to allow more passing opportunities by removing the clean line making it easier to use more of the track.

IMO it could work in the early parts of the race but would make passing just as hard it's now in the later part of the race.
