The energetic 18-year-old, who was acquired from Penarol in his native Uruguay earlier this month, operated mainly on the right of a front three for Neil Wood's side but seemingly had the licence to roam as he enjoyed getting on the ball in more central areas to good effect.
It was from there, in the middle of the penalty area, that Pellistri almost put United ahead in the 25th minute with a well-struck shot from Shola Shoretire's left-wing pull-back, but Everton goalkeeper Joao Virginia stuck out a leg and a dream debut goal was denied.
The Uruguayan's willingness to receive possession and drive at the opposition defence led to him being on the end of some robust challenges and he was probably the most fouled player on the pitch.
