Redknapp reckons Manchester City striker Balo â€ścrossed the lineâ€ť and showed a lack of respect by grappling with his manager.
But he also says Mancini should have handled the situation better and not allowed himself to get involved in the bust-up with one of his players.
Redknapp, 65, said: â€śHeâ€™s a top manager but you canâ€™t get like that with players now. You canâ€™t be doing all that shouting and screaming at them.
QPR boss admits even he - one of the best man-managers in the game - could not manage Mario
â€śIt probably used to happen years and years ago, managers would be throwing cups and all that. But those days are long gone, you donâ€™t get any anywhere behaving like that towards players now. You lose their respect.â€ť
