Mauricio Pochettino has described Tottenham midfielder Dele Alli as like a "wild horse" that can never be tamed.
Alli has become one of Pochettino's most trusted performers at Spurs and has scored four goals for club and country already this season.
The 20-year-old's attacking talent comes with a fiery personality, however, that has landed him in trouble in the past.
Alli was handed a three-match ban at the end of last season for punching West Brom's Claudio Yacob and he was lucky not to escape punishment in the Europa League when he kicked Fiorentina defender Nenad Tomovic.
