Mercedes motorsport boss Toto Wolff has suggested one of his drivers will require psychological counselling should they lose this year’s Formula One world title by the controversial double-points system.

For the final race of the campaign, which this year will be in Abu Dhabi in November, the top 10 drivers will collect twice the normal amount of points for a race, with the winner enjoying 50.

When announced in December, fans worldwide vehemently criticised F1 supremo Bernie Ecclestone’s plan, believing it to be too artificial and a disservice to the sport.

Wolff has never been a fan either, and with it now becoming patently obvious either Lewis Hamilton or Nico Rosberg will win the crown, he has openly joined the chorus of condemnation.

Following a German Grand Prix won by Rosberg, with Hamilton a superb third after starting from 20th on the grid to limit the damage to his teammate, the gap between the two is now 14 points.

With it likely to remain nip and tuck between them over the second half of the season, Wolff said: “I would be very surprised if it didn’t come down to Abu Dhabi. So maybe Bernie was right, that double points is going to keep the championship open until the last race.

“But I don’t think it’s fair. The reason we did was because the commercial rights holder is head of sponsorship and he cares about the TV audience and the need to keep the excitement until the end."

Should a driver lose by such a system, Wolff believes it would be hard for that man to bear.

“Neither of them will care if they won it that way,” added Wolff. “But the one who loses on double points will need some psychological treatment – although we’re not there yet.”
