Chelsea will be out to prove a point to Manchester City's �32million man Robinho when they travel to Eastlands on Saturday, according to goalkeeper Petr Cech.
The 24-year-old Brazilian was a long-term target for the west London club but instead opted for a shock transfer deadline day switch to Manchester City - now backed by the billions of the Abu Dhabi United Group.
"He needs to play well for Manchester City and we want to show him on Saturday he made a decision that is not perfect for him really," Cech said.
The two Barclays Premier League big spenders will go head to head in Saturday afternoon's late kick-off and Chelsea are determined to show Robinho - who had publicly stated his desire to move to Stamford Bridge, only to suddenly have a late change of heart - just what he missed out on.
"In the morning he says he loves Chelsea and he wants to be part of Chelsea, and then a few hours later he signs for another club, but it was his decision," Cech added.
"He is a great player and the sort of player who can entertain people so for the Premier League maybe he is good - but we will see how he is going to cope with the pressure now."
Manager Luiz Felipe Scolari will hope all of his returning internationals are fit after losing combative midfielder Michael Essien for up to six months on the sidelines after sustaining a ruptured anterior cruciate ligament while away with Ghana.
Cech said: "It is a blow because he has been a great player for us since he came, but we have a large squad and we need to cope with that.
"I wish him a speedy recovery because we will all need him."
