Sunderland goalkeeper Simon Mignolet says they go to Chelsea full of confidence.
Mignolet insists the prospect of three points isn't the stuff of fantasy.
He told Absolute Radio: "Of course we can. I think if we are on a good day and we do our job like we are supposed to do then we've got a good chance, yeah."
