Toto Wolff is convinced that he won’t have to change his driver line-up to resolve the Hamilton-Rosberg war, the Mercedes motorsport boss said yesterday.

Wolff has warned Lewis Hamilton and Nico Rosberg that he would consider axing one of them if they couldn’t resolve their differences.

There has been an uneasy truce since the incident at the Belgian Grand Prix a fortnight ago when Rosberg effectively ended Hamilton’s race by colliding with the Brit’s car.

Wolff had told BBC Radio 5 Live: “If we are not able to manage the two of them following the Mercedes-Benz racing spirit, then we need to admit that and take decisions and take consequences of having a different line-up probably.”

But he later made clear that was a “very worst-case vision.”

He said: “At this stage we are very happy with the line-up, our two drivers, we have always said that.

“We trust them, we had a very good, clear discussion with the two of them, that what happened in Spa shouldn’t happen.

Rosberg held sway in yesterday’s Italian Grand Prix practice runs, though his teammate was plagued by electrical issues.

Hamilton completed only 16 laps to the German’s 41 and may have finished top of the timesheet but for traffic when he did finally take to the track with 25 minutes remaining.
