Hamilton is currently experiencing the first significant winless streak of his F1 career, facing two consecutive seasons without a victory.
And while Rosberg acknowledges the potential shown by Mercedes in Austin in October, he stresses that consistency remains the biggest hurdle to overcome in providing Hamilton with a car capable of securing his record eighth drivers' crown in 2024.
Consistency is key
“We’ve seen flashes of brilliance from the Mercedes team just recently," Rosberg told the Daily Mail. "They lack consistency. But look at Austin. They were challenging for the win there and actually had the fastest car over the weekend.
“So, we’ve seen that they’re starting to understand the car and they just have the problem that you still lack consistency.
"They still lack in straight-line performance but they are starting to understand all that.
“I believe in Mercedes’ ability because I was there. I know how strong they are. It’s always still the same people. So, certainly, there is a chance that Hamilton could once again fight for the championship next year.”
