The rumours have understandably upset Spurs fans, although Redknapp believes it is far from guaranteed that Pochettino will accept a move to Old Trafford.
“It's a difficult one," Redknapp told BBC 5 Live. “He's obviously getting very, very well paid where he is. It's a good club, they've got a great training ground. They've got a brand new stadium coming.
"He's got a good team. He's got to go and build a team at Man United. For me they're still way short of being a team that could win the league again. I think the back four needs absolute surgery there.
“I still think they're quite well short of where they want to be. So I don't know — does he jump ship and go and start again and look to rebuild there where he's absolutely loved at White Hart Lane?
"It's a difficult situation for him I'll be truthful I would think his life's pretty good at the moment. He's absolutely there idolised by the fans. I think it would be difficult for him to leave personally. Even though Man Utd is an amazing football club, we all know that."
