Pogba is the most expensive player in world football, after moving to Old Trafford for £100 million last summer (Daily Mail).
However, Redknapp believes that Alli is a superior talent, after watching the pair perform this season.
“When they signed him I said Pogba was a fantastic player, but I think Dele Alli is an even better player,” Redknapp, who used to manage Tottenham, said.
Pogba has made a sluggish start at United so far, and he has struggled to live up to his price tag.
The powerful midfielder was off the pace again last night, as United drew 0-0 with Liverpool at Anfield.
Alli has made 10 appearances for Spurs in all competitions so far, and he has hit the back of the net on three occasions.
Pogba, meanwhile, has made nine appearances for United - but he has only got on the scoresheet once.
