Chelsea boss Rafa Benitez is wary of Norwich City's quality today.
Chelsea are playing nine games in just 27 days.
Benitez said: "We have to manage the squad, we have to be sure that we can manage the fatigue that is there.
"Norwich were doing well: at the beginning they were under pressure, not too many good things; but after that the did well. They lost the other day, but still you can see that their team is professional and will be a top team."
