The former West Ham man had only good things to say about the rising Tottenham Hotspur star.
The 20-year-old enjoyed a phenomenal breakthrough season at Tottenham, scoring 10 times and setting up 12 more to win the PFA Young Player of the Year award.
Despite his youth, there is a toughness to the midfielder, who was hit with a three-match ban toward the end of the 2015-16 campaign for punching West Brom's Claudio Yacob.
But Ferdinand has suggested that he is perhaps most impressed by what the England international has upstairs, noting his football brain and how he does not run around like a "headless chicken" on the pitch.
"He's got no fear factor and he looks like he understands the game," the former West Ham and QPR defender said on ESPN.
"He doesn't run around like a headless chicken. He actually understands the game which, for someone of his age, can only bode well and I think he's got a bright, bright future."
Indeed, the Spurs man could see his stock rise even further if he goes on to enjoy a successful Euro 2016 with England, which he might well do.
Nothing seems to be faze the young man and such a mental toughness can only yield positives and lots of them for Tottenham.
The Three Lions kick off their Euro 2016 campaign by clashing with Russia on Saturday in Marseille.
