Tottenham assistant manager Cristian Stellini admits he's studied the work of Chelsea manager Graham Potter.

The pair will face-off in Sunday's derby, with Spurs manager Antonio Conte continuing to recover from surgery.

Potter is under plenty of pressure from sections of the Blues fanbase and there has also been an ongoing debate about whether he gets angry enough with his team, the officials and what happens in matches.

Stellini was asked what makes him angry and he admitted it was not so much football, but rather his now grown-up children - two girls and a boy, aged 23, 21 and 19.

"Everyone is different. Also In Italy we have coaches who show a different behaviour so it is not important. What is important for me is that our players play a great match," said the Spurs assistant head coach. "Sometimes I get angry, [with] my children more than anything! They do what children do normally: they grow, they create problems - and the older they are the bigger the problems are so that makes me more angry than anything.

"Anger sometimes comes from love. Also a manager, if he loves his team and he loves his job, sometimes he is angry. Maybe you don't have to show this anger because you have it inside, and you transfer it to your team after."

Stellini admitted that he was fascinated by Potter's Brighton side and studied the coach and his work when he arrived in England with Antonio Conte.

"Yes [he's a good coach], I studied Potter since I arrived here because he was a manager that in Brighton last season, I follow Brighton a lot, because it surprised me the way they play, the way they change system many times and the way they were good to challenge with Potter," he explained.

"We played many games against them and every game was different so understand the decision he took last season was really interesting for me and for sure he is a great manager."
