Mercedes GP driver Nico Rosberg says rear tyres vital at Monza.

Nico Rosberg: Monza is different to all of the other circuits and the cars reflect that. They have to go very fast along the straights and I hope that we’ll do a bit better here we have at previous tracks this year. As far as tyres are concerned, this track is really hard on the rears and we’ll have to see how long they last when we’re using full tanks before we decide how many pit stops we’ll have to make.
