Sturridge is in club's record books after a third goal in his first three consecutive games.
Carra said: "He is a good player and has linked up really well with Luis. He's scored three in three now. If he does as well as Ray Kennedy then he will have done well.
"I'm sure Kennedy didn't do that stupid dance, though!
"We all want to play in a team with good players. It's early days, but it looks a good decision to bring him in."
