The Tigers are at Newcastle today.
"When you see them last week winning at Villa and look at the team they can field when (Loic) Remy is fit, when (Papiss) Cisse is back, when (Hatem) Ben Arfa is fit and (Yohan) Cabaye is still there...they are a very good side, no question about it," he said.
"Like the rest of us when they are missing two, three or four big players of course it can be a problem.
"One game is a crisis in this day and age and after the first game of the season Arsenal and Newcastle were in crisis. Since then they've gone on to pick up seven points and had back to back wins. It's going to be difficult for us."
