The cultured midfielder, who has just completed a move from Liverpool to Tottenham, will be in the BBC television studio for World Cup 2002.
Having been denied the chance to challenge for an England place by persistent injury, Redknapp will instead give viewers a player's insight during the tournament.
He was capped during Euro 96 and has played alongside many of Sven-Goran Eriksson's stars.
Redknapp has won a host of domestic honours and was the club captain at Liverpool, the team he joined in 1991 during Kenny Dalglish's tenure as manager.
He is famously married to pop star Louise.
