Monza will give a clearer indication of how good Senna is in the Renault team boss Eric Boullier said.

Do you think Monza will provide a greater indication of ‘the Bruno effect’?

Eric Boullier: Yes, it’s difficult to draw too much from one race alone (Spa), whether that’s in terms of who is in the race seat or the effect of the upgrade package, but Monza should give us a clearer indication as to how things are going. Monza is always a difficult track because it requires a low downforce set-up; it has high speed corners and high speed straights. After the steps we made in Spa, I’m confident we will have a progressive weekend in Italy too.
