Redknapp said: "Benji's scoring goals now which is great. He's always worked his socks off and done great for us but he's never really scored too many - and now he can't stop scoring.
"Ever since I bought him he's done an unbelievable job for us. In his first season he couldn't score a goal for 15 games but he never stopped working, and last season he weighed in with six.
"The fans love him because he is a fantastic fellow and he just loves playing the game. He's always got a smile on his face and now he's adding goals to his play, which is great for him."
