Ange Postecoglou admits taking the reins of Nottingham Forest was a mistake only he can be blamed for.
Postecoglou coached eight winless games at Nottingham and was sacked after 39 days, the second-shortest managerial tenure in English Premier League history.
His Forest stint was a steep fall from grace following his two seasons with Tottenham Hotspur, where he ended a 17-year trophy drought with a 1-0 win over Manchester United in the UEFA Europa League final in May last year.
