Harry reckons Wenger has become a Nutty professor...
Spurs boss Redknapp said: "He has joined the nutters, you know. In fact, he is one of the key nutters. It just shows you what happens in football."
Wenger is back on the touchline against West Brom today after serving a one-match ban for shoving fourth official Martin Atkinson at Sunderland.
Redknapp said: "When Arsene first came to England he was like a professor watching the game.
"All the other nutters were jumping up and down shouting and screaming, hollering and hooting and this man was not like those idiots.
"But it is affecting him now. He's no longer sitting there. He is up there arguing with everybody. When you start losing a few games it all changes."
