Rafael Benitez has praised David Ngog. Benitez was pleased with the way Ngog took his goal against West Ham last night and believes he will do a good job of covering for Fernando Torres. "When you play instead of Fernando people will always talk but I have confidence in him," said the boss. "He can score goals and he did well tonight. He had one or two chances, he has very good movement and always keeps the defenders busy. "He knows he has played a lot of games this season and he has to work hard. He is someone who is trying to improve and can do a good job for the team."
