Lewis Hamilton believes Max Verstappen could be in the fight to win the 2019 world championship.
"Max drove very well throughout last year, showing his consistency," 2018 world champion Hamilton said.
"He was right up there with us many, many times, so if his team does the job and delivers a platform with which he can compete even closer with us, then, of course, he'll be in the fight," the Mercedes driver added.
Ferrari's Sebastian Vettel, the 2018 runner-up, agrees that 21-year-old Verstappen is ripe for the title.
"I think he's got all the ingredients," said the German.
"I think there's a couple of guys out there who have these qualities and Max is certainly one of them."
