With news that the Red Devils are reportedly interested in the ex-England defender circulating, Redknapp wrote in his column for The Sun that the move would not be as bad as many people think.
35-year old Campbell walked away from a lucrative five-year deal with League Two outfit Notts County earlier this season and is currently a free agent looking for a new club.
He is aware of United's interest and has spoken of his desire to join the English champions and Redknapp believes that the former Tottenham, Arsenal and Portsmouth centre-half would be a great acquisition to Sir Alex Ferguson's squad.
'Campbell can prove, as Swedish star Larsson did, that he still has the quality to play at the very highest level and I'm not surprised at the reports tipping him for a Premier League return.
'United went on to win the Premier League title that season, two months after Larsson, now 37, went home to Sweden with Sir Alex full of praise for the way he handled himself.'
Redknapp wrote of United's current defensive problems and said Campbell would be a great person to bolster the club in that area.
