Ange Postecoglou was left seething after Tottenham were beaten by Manchester City on Tuesday and took aim at his own supporters for cheering on Pep Guardiola's side.
The Australian - who has shown his frostier side in recent weeks - was furious at his players and the club's fanbase as defeat meant Spurs missed out on qualification for the Champions League and labelled Tottenham's foundations as 'fragile'.
Postecoglou also confronted a supporter in the stands after some home fans at the game celebrated Man City's win due to it damaging rival Arsenal's Premier League title hopes.
