Redknapp admits he could count on Jermain Defoe giving him details of the Spurs line-up when the pair were together at Fratton Park!
Reacting to criticism of England coach Fabio Capello's approach, Redknapp wrote in his column for The Sun: "If you told the players your team on a Friday then one of those left out would cop the hump and start telling his mate on the opposition what exactly was going on.
"One of his old mates - generally one sulking at being left out - would have texted him the whole shabang as a way of making a point.
"It goes on at every club and nowadays players from every country are pals so it would happen at the World Cup too.
"Capello is right to keep his teamsheet in his pocket."
