Lambert believes De Laet will complement the current group well.
"Ritchie will be great for us," said the Canaries manager.
"He is young and one of his main strengths is pace and he comes from a great club where he's played first team football. He will come in and help the other lads out.
"Ritchie has played a lot of first team games out on loan last season and I am sure he'll do great for us."
