"I'm really pleased for Steven. It is fantastic for him because he was competing with a lot of good players," said Benitez.
"For him to be named player of the year is massive credit to him and shows just how much he has achieved.
"He has scored 23 goals for our team already this season and clearly he has had another fantastic season.
"Everyone at the club is delighted that he has been given this award.
"When Steven was told that he was the winner the first thing he said to me was thanks to the staff and thanks to his team-mates.
"This is a very positive reaction and shows how much Steven is part of a team."
