Roberto De Zerbi is buoyed by Tottenham's recent form, despite their Premier League goal drought, insisting they are still on the right track.

Spurs have played four matches without scoring in the top flight, going 407 minutes without a league goal.

They started the season with back-to-back defeats but have since drawn their last two 0-0 with Nottingham Forest and Everton.

Their next match is against Liverpool in the EFL Cup third round, with Spurs having found their goalscoring touch last time out in the competition with a 5-1 thrashing of Charlton Athletic.

Despite their tough start to the season, De Zerbi remains optimistic that Spurs will only continue to get better.

"Ten days before the Everton game, we started working with all the players in the squad. I think we're working well. We played 30 minutes, 25 minutes very well. In that moment, we could score two goals," De Zerbi said.

"Then we lost maybe the confidence because we didn't score. For sure we have to improve. For sure, I have big confidence in my players; they are very good players.

"We have to improve, yes. We can say the coach has responsibility if we don't score, yes, I accept, no problem. We didn't win any game so far, yes. We are disappointed; sorry for that.

"But we have other positive things – like I said, we didn't [concede goals] in the last two games, and the things we have to improve, we start our work. Nothing changed in my project and my idea."

Spurs have won just one of their last 30 away games against Liverpool in all competitions (D8 L21), and none of their last 17 (D5 L12) since a 2-0 Premier League win in May 2011 under Harry Redknapp.

They have also been eliminated from five of their last seven EFL Cup ties against fellow Premier League opponents.

Indeed, Spurs have lost four of their last five away games against top-flight sides in the competition (D1).

De Zerbi will be without Sandro Tonali, who suffered a knock against Everton, but he will be hoping his side can click further up the pitch as they did against Charlton when they have five different goalscorers.

"[Dominic] Solanke is a good player, and I'm sure he has to improve his physical condition and to stay positive; he's able to score many goals with us," De Zerbi said.

"Savio and [Omar] Marmoush didn't play many games in Manchester City because they were not the protagonists. Here the situation is different; they have more responsibility, they have to adapt and understand the situation is changing, but in terms of quality, both players are very good.

"Mathys Tel, Conor Gallagher, James Maddison not in the best condition, [Mohammed] Kudus not in the best condition yet. All these players can play as a number 10, but they have to attack the space, attack the area sometimes.

"[Andy] Robertson crossed many times in the first half, and the opposite midfielder, Mateus Fernandes, didn't come in the area; this part we have to improve.

"Keeping the defensive phase, which is important. My style has been to score goals and attack, and I don't want to change. But sometimes you have to create more chances, more potential chances."
