The England international has only recently made his return to the Liverpool first team after a string of injuries restricted his number of appearances this season.
Sturridge is expected to play a big part in Roy Hodgson’s plans for England at Euro 2016 in France this summer.
Sturridge has scored four goals in the Premier League for the Reds so far this season but has been limited to just five starts and seven appearances in total in the top flight.
Reports in the British media in recent days have suggested that PSG are interested in luring the forward to the Ligue 1 club in the summer transfer window.
And former Liverpool midfielder Redknapp insists that he has not been surprised to see Sturridge linked with a move to Parc des Princes.
Writing in his column for the Daily Mail, Redknapp said: “This is such a difficult one for Liverpool.
“They will be desperate to make it work with Sturridge, but they know his injury history and if Paris Saint-Germain offer silly money, then who knows?
“The last thing you want to do with a world-class player like that is sell him, see another club cure his injury problems and get 40 games a season out of him.
“I’m not surprised PSG want him but as for filling Zlatan’s boots, that’s a tough ask. Ibra is almost impossible to replace!”
