Dier has had a whirlwind season so far, becoming a key player for Spurs and earning his first senior England start against France on Tuesday.
The 21-year-old has impressed many observers since moving into a defensive midfield position, and Crooks believes he has a huge future at White Hart Lane.
“Dier has been one of the finds of the season,” Crooks said. “I think he’s a really important player for Tottenham. He looks imposing on the pitch, he can play anywhere across the back line and he can play that defensive midfield role that he’s suddenly made his own.
“He’s not afraid to go looking and hunting for goals too so I think he can be the real deal. In my opinion he’s a future captain of the club, and such an impressive talent.”
Dier has formed an impressive partnership with Dele Alli at the heart of Spurs’ midfield, and the pair have earned plenty of plaudits for their performances.
The Lilywhites have gone unbeaten through their last 11 Premier League matches, and the protection the youngsters have given their defence has been a major contributing factor to that run.
Dier has shown himself to be a combative tackler in the centre of the pitch, while his distribution has also caught the eye.
It will be important that the hot prospect does not get carried away by the hype that he is generating at the moment, though, and he will be hoping to continue his brilliant form when Spurs take on capital rivals West Ham United this weekend.
