Redknapp has strongly criticised Tevez after the striker refused to come onto the pitch in City’s Champions League defeat against Bayern Munich on Tuesday.
Redknapp said, when asked about Tevez: “We couldn’t afford him, no chance.”
The Spurs boss added: “He is a great player, but I can’t condone what happened yesterday. It was unbelievable.”
“I felt sorry for Roberto Mancini to be put in that situation. It wasn’t fair. It wasn’t right,” said Redknapp.
“It wasn’t right for Man City and was not right for football. I can’t believe it. It shouldn’t happen and can’t happen.
“When you look at that, you wonder what Joe Mercer and Malcolm Allison would have thought of it and all the great Man City people. The great players like Summerbee, Bell, Lee.
“To see a player do that, refuse to come on and play in a Champions League game is beyond belief.”
When asked what he would do if he was in the same situation as Mancini, Redknapp said: “I don’t know what you can do now, he holds all the aces.
“He gets his wages every week and eventually, if you want to give him away, someone will give him a fortune because it’s cheap or there is no doubting he is a great player.
“It’s a problem that only Man City can deal with now.”
