The two Mercedes drivers head into the final four races, with Rosberg 33 points ahead of Hamilton. Many have put Rosberg's lead down to the unreliability of Hamilton, however veteran Massa feels that Rosberg deserves to win.
“Nico has had a better year than (Lewis) Hamilton,” the Williams driver said.
“He has done a good job on the track, with the team and on the psychological side,” Massa added. “There is no doubt that, this year, he deserves to be champion more than Hamilton.”
Also speaking about the title battle was F1 supremo Bernie Ecclestone. He says that it would be good for Rosberg if he won the championship, but Hamilton makes a much more interesting champion.
"If Nico won the title it would be good for him and good for Mercedes but it wouldn’t necessarily help the sport because there is nothing to write about him,” he said.
