Redknapp tried to sign Beckham last January after the LA Galaxy star spent time training with Spurs following the end of the MLS season.
Beckham’s current contract at LA Galaxy expires in December and the midfielder has been linked with a number of clubs in Europe.
“It’s a difficult one,” admitted Redknapp. “You would love him around your football club. As I have said many times, you couldn’t get a better professional and a nicer guy.
“But he wants to play and it would be difficult because I have a lot of players here at the moment in those sort of positions, so it wouldn’t be easy.
“But who knows? Let’s see what happens when David’s contract runs out.”
