The striker has once again struggled for fitness this season, with a series of niggling injuries continuing to limit his game time.
He returned for Liverpool in the midweek loss to West Ham United in the FA Cup though, putting in a decent display to remind Reds fans what they have been sorely missing.
And Redknapp says if the striker can maintain his fitness, he should be starting ahead of both Kane and Vardy for England at Euro 2016.
“Harry Kane and Jamie Vardy have had fine seasons for their clubs but if Daniel Sturridge can get himself fit again, he has to lead England’s attack at Euro 2016,” he told the London Evening Standard.
“He is that good. In all honesty, he is probably England’s best player. He is a match winner and sometimes he does things that you see only Lionel Messi and Neymar do.”
“To come off the bench so short of match fitness and play like he did at West Ham on Tuesday night was very impressive. He’ll make a massive difference for Liverpool.”
Redknapp’s opinion is not one that many would agree with at present, given the form of the Tottenham Hotspur and Leicester City stars this season.
Vardy is the leading goalscorer in the Premier League with 18 to his name, while Kane has 15 to his name despite a slow start to the campaign.
That kind of form should see both of them far ahead of the Liverpool man in the pecking order despite the obviously quality that Sturridge brings to the table when fit.
