The 19-year-old Alli, who extended his contract with Spurs to 2021 on Tuesday, has been a revelation for the club this campaign, having netted five Premier League goals in 18 appearances.
After a string of fine performances, Alli caught the eye of England manager Roy Hodgson, who handed the midfielder his first appearance for his country in the 2-0 win over Estonia in October.
"Alli needs to feel free on the pitch and we need to help him improve in different positions because a versatile player like Pogba has a big, big value," Pochettino told British media.

"A player like Dele Alli, we need to help him to improve, not to put him in a box.
"When he plays like a No. 10 he makes the movement like a striker and when he plays No. 8 or No. 6 he plays like a holding midfielder. He is very clever and that's his best quality. It's how he reads the game."
Tottenham, fourth in the table with 36 points from 20 games, host second-placed Leicester City in the league on Wednesday.
