The Dane left Spurs being jeered by his own fans in his final games.
He recalled to the BBC: "I was blamed for many things at Tottenham because I was seen as an evil genius.
"When I said that I did not want to renew my contract, everyone was busy with my departure. Every match the same question: 'Is he going away, isn't he going away?'
"A lot of people talked about it. Even the fans on the street were doing it: 'Thank you, goodbye and good luck.'
"I felt that I just had to be honest.
"I didn't want to hide, like so many players do. Everyone is different in that. I was just being honest and publicly expressing my feelings.
"I read that I had a bad influence on Tottenham's dressing room, that I was a 'persona non grata' because of my desire to leave. To be honest: Every player would consider a departure if something interesting came by. I was only the one who dared to say it openly."
