England head coach Stuart Lancaster has praised the attitude shown by James Haskell since his return to the squad.
Haskell is poised to win his first cap since last year's World Cup against South Africa on Saturday and Lancaster believes that the flanker's work ethic makes it an easy decision to select him.
Lancaster said: "He is just enthusiastic and wants to do well, he wants to improve. He is always working at the end of training on his skills.
"He has brought a lot of energy to the side and he has certainly brought a lot of experience.
"We are looking for him to bring his physicality to our back row as a defender and a ball-carrier."
England have lost the first two Tests against South Africa.
