De Zerbi’s side are alongside Aston Villa and Coventry in not scoring a single goal in their opening three Premier League games of the season.
Spurs and Forest played out a drab 0-0 draw at the City Ground, leaving the London side down in 17th, the position they’ve ended the past two seasons in. To make matters worse, Spurs didn't have a single shot on target against Forest.
The unwanted stats don’t end there. This marks the first time since 1974 that Tottenham have failed to score in their first three league games.
Despite all that, De Zerbi still believes his side have the ability to score ‘many goals’.
"In terms of performance, I am very, very proud. I'm delighted to watch my players fight like this. We didn't concede risk to concede goals," he told BBC Sport.
"We are working now, because we started last Thursday, very happy for the spirit, the attitude, the behaviour of the players. The players who played 90 minutes, 70 minutes, 20 minutes, 10 minutes.
"This is our way, great qualities of the players. The human level of the dressing room is great; now we have to work and improve at all levels of football.
"Our mood is to win, to win, to win. But I think we have to stay calm to keep the confidence in ourselves. Then I think we have the players good enough to score many goals like (Dominic) Solanke, Savio, (Omar) Marmoush."
