Whittaker is now playing a key role for the Canaries after recovering from an ankle injury that KO'd him after his summer move from Rangers.
Snodgrass said: "He's been unlucky, especially as he's spent most of his career in Scotland and has only now come to England.
"But he has been terrific in the last few games. I'm delighted to see his career back on track. He can play a few positions, but I think he'd be the first to tell you right-back or left-back are his best."
