Ange Postecoglou says "Spurs does crazy things to people" in response to Arsene Wenger's suggestion that the winners of the Europa League should not qualify for the Champions League.
Former Arsenal manager Wenger, now Fifa's chief of global football development, has questioned why the winners of the Europa League qualify for next year's Champions League.
Postecoglou's Tottenham have a 3-1 lead going into Thursday's Europa League semi-final second leg at Bodo/Glimt's Aspmyra Stadion.
But they are 16th in the Premier League table, while Manchester United - who have a 3-0 lead over Athletic Club in the other last-four tie - are a point ahead in 15th.
