Pacheco made his Premiership debut as an 80th minute subsitute in the 2-0 win over Wolves on Boxing Day and instantly adapted to the pace of the game. His cameo performance earned him the praise of his manager.
"Dani is a player with quality who has played really well for the reserves," said Benitez.
"He was going forward and is not scared to go against the defenders. It was a real positive because he has shown he has quality."
