Even after a convincing, controlled win that sent his Tottenham side back to the top of the English Premier League table, Ange Postecoglou had a warning for his players.
Spurs have begun the season at breakneck pace, registering seven wins in their first nine matches as they lead the league by two points from champions Manchester City.
On Monday night, they eased to a 2-0 win over London rivals Fulham to give Postecoglou a record 23 points from his opening nine games as an EPL manager.
