De Zerbi put pen to paper on a reported five-year contract at the end of last month, with Tudor departing after only claiming one point from his five league matches at the helm.

Former Marseille boss De Zerbi takes over a Spurs side that now sits inside the relegation zone after West Ham United's 4-0 thrashing of bottom club Wolverhampton Wanderers n Saturday (AEST). 

The Italian is Spurs' third manager of the season, and his first match at the helm comes in a tricky trip to The Stadium of Light to take on Sunderland.

"I am not better than Thomas Frank or Igor Tudor. I consider them very good coaches, but I try to bring my style, myself, my character, personality and passion to help the players show their quality," he said in his first press conference as Spurs boss.

"And then to achieve our target. The most important part is the target [avoid relegation]. My style is one part. One part is the style of play and the other part is about the character and personality.

"I don't have time for principles or build-up, I want to give organisation with the ball and without the ball. What I want to do and what I want to achieve is the character.

"The right spirit, courage to play and attack. The DNA of this club and squad is to find the goal, to score. In this part, I will be able to transfer my principle."

Sunderland signed off for the international break with a 2-1 win over rival Newcastle United, moving it up to 11th in the Premier League and within six points of the top five.

Chemsdine Talbi and Brian Brobbey's second-half strikes cancelled out Anthony Gordon's 10th-minute opener to continue Sunderland's impressive record at the home of its rival.

But Black Cats boss Regis Le Bris acknowledged the task ahead of his players, especially with De Zerbi now in charge of Spurs. 

"He is a great coach, has strong experience, good ideas and a clear identity. He will be the best version of Roberto De Zerbi if he is himself, not someone else," Le Bris said.

"So I think he will go all the way and it will be interesting. Performance in football is complex. It's often a question of confidence, belief.

"Psychology is important. Probably the most important thing is to implement this belief.

"Tottenham are a big club, but they have struggled to generate momentum this season, and you never know how you create this vicious circle of injuries, efficiency, doubts.

"It means that this league is unforgiving, really demanding, it is hard to break. They have good quality, but when you have doubts it is hard."
