Sunderland travel to Stamford Bridge on Saturday.
The Blues have dominated the headlines over the past 24 hours following the sacking of Jose Mourinho, a decision which has drawn plenty of debate among supporters and pundits alike.
Chelsea’s current position of 16th in the table is a huge shock considering they still possess the bulk of their title winning squad from last season – quality which is permanent, not temporary.
Sunderland go to Stamford Bridge arguably at the worst possible time, and Redknapp feels the hosts’ better players will be keen to really step up and show their worth.
“There has to be some kind of reaction from Chelsea now. I’m really expecting the big players in that Chelsea side to step up and show us how good they are at the weekend,” Redknapp said.
“It’s not good news for Sam Allardyce, but I do expect Chelsea to win this game, and comfortably.”
Sunderland have had mixed fortunes under Allardyce thus far, winning three and losing five of their eight matches under the former Bolton Wanderers boss’ guidance.
The Black Cats are in desperate need of added creativity upfront and their recent 1-0 home defeat to Watford illustrated exactly where they ultimately come up short.
January will prove a big month for Sunderland, though before that they have four testing matches ahead with games against Manchester City and Liverpool coming up after their trip to West London.
Allardyce will be hoping his side can cause unrest among the home support by frustrating the hosts and keeping it tight at the back, though planning it and doing it are two separate things altogether.
