WATCH: F1 Report Russian GP

Natalie Pinkham is joined in the studio by Dominic Harlow and Marc Priestley to preview this weekend's Russian GP.

With the proposed regulation changes for 2017 set to be finalised in the coming days, this week's F1 Report guests debate how they might affect racing in Formula 1 next year.

Former McLaren mechanic Priestley and former Williams senior operations engineer Harlow will also discuss whether the changes in key personnel at Mercedes are having an affect on Lewis Hamilton and Nico Rosberg.

The pair are having contrasting seasons, with the German currently leading his team-mate in the Drivers' Championship by 36 points.

Hamilton has happy memories in Sochi having won the two previous grands prix, and our guests look ahead to this weekend's event with Ferrari and Red Bull hoping to bring the fight to Mercedes once again.
