Mauricio Pochettino is determined that Serge Aurier will not upset his Tottenham dynamic and jokingly promised to "headbutt" the defender if he steps out of line.
The full-back was a controversial figure at times at former club Paris Saint-Germain, most recently receiving a suspended two-month jail sentence for assaulting a police officer outside a nightclub.
Spurs completed a deadline-day move for Aurier last week and Pochettino has addressed the 24-year-old's discipline, insisting that he trusts his new signing.
"I said to him, 'I will kill you' - I [would] headbutt him," Pochettino joked.
"I think it was good - we had a long chat. He knows very well how we are, what we expect from him and, for us, it's so important - not only him, every player - how they behave here in the squad.
"We need to keep the dynamic we have created. I trust him. I am confident that he can succeed here and help the team to achieve the things we want.
