Jacques Villeneuve thinks Nico Rosberg will bounce back from losing his world championship lead for the first time in 2016.
Rosberg’s Mercedes teammate Lewis Hamilton has ended his run of mediocre form with five wins out of the last six races, racing into a 6 point lead in Hungary.
But team boss Toto Wolff predicted: "We’ll see it swing through the season.
"My feeling is that the championship will go to the end."
1997 world champion Villeneuve agrees, telling the German newspaper Bild: "The pendulum swings between one and the other.
"I see them as absolutely the same and I believe that, in the end, Nico will be the one in front."
