Tottenham Hotspur Supporters' Trust has requested a meeting with the club's board to discuss the 'short and long-term strategic vision' for the club.
Spurs have suffered successive Premier League defeats to London rivals Crystal Palace, Chelsea and Arsenal.
They appointed former Wolves boss Nuno Espirito Santo in June following a protracted search for a new manager after Jose Mourinho was sacked in April.
But, despite topping the table after beginning the new campaign with a trio of 1-0 wins, the Portuguese coach's position is already coming under intense scrutiny on the back of recent poor results, including Sunday's 3-1 north London derby loss at the Emirates Stadium.
