United are enduring their worst start to a Premier League campaign in 30 years and Redknapp believes the Red Devils can already be ruled out of a top four finish.
He added: “I can’t see them finishing in the top four, no way. I’ll be honest with you, I watched their Arsenal game the other week and there wasn’t a player on the pitch who would have got in the Man United team a few years ago.
“(Roy) Keane, (Paul) Scholes, (Ryan) Giggs, (David) Beckham, (Rio) Ferdinand, (Nemanja) Vidic. Andy Cole. Dwight Yorke. Teddy Sheringham. They were difference class.
“Everyone keeps saying how great the game is nowadays but there isn’t one player on that pitch who would have got into those teams in my opinion.”
