Tottenham Hotspur must change their mentality if they are to end their trophy drought, says assistant coach Cristian Stellini.
Spurs suffered a surprise 1-0 defeat by Sheffield United of the Championship in the FA Cup on Wednesday.
That leaves Tottenham with the Champions League as their only realistic hope of ending a 15-year trophy drought.
"The mentality is the reality we showed in the last game," said Stellini.
"This is the mentality. The approach was not good and it's not the mentality we need.
"We have to change from this starting point to the future.
