Wolves boss Paul Lambert insists the onus is on Chelsea ahead of Saturday's FA Cup clash at Molineux.
Lambert's team have already accounted for Stoke and Liverpool in this season's competition but face their toughest task to date on Saturday evening when Antonio Conte's Premier League leaders come to town.
Stoke rested some players against Wolves while Liverpool played several youngsters, but the talent at Conte's disposal is on a different level in comparison.
Chelsea are eight points clear at the top of the table and have been defeated only once since October, while Wolves are 18th in the Championship and have lost their last three league matches.
