The 24-year-old French-born Algerian made his full debut against Spurs and earned plaudits from Mick McCarthy.
"The gaffer has brought him in and he's a big, strong lad who's good on the ball," said Craddock.
"He's got a nice shot on him as well so hopefully he'll stick one in the top corner soon.
"He can really play and he showed that against Tottenham.
"It's about playing in the right areas at the right times and fitting in and he did that against Spurs.
"It was a tough game for anyone but he did well and credit to him and the other boys."
