Chelsea boss Jose Mourinho was angry with Mohamed Salah and Andre Schurrle after their Capital One Cup win over Shrewsbury Town.
Salah and Schurrle were handed rare starts, while Nathan Ake, Kurt Zouma and Andreas Christensen also got game time.
Mourinho said he was disappointed by certain performers and knew his team to face Queens Park Rangers at the weekend, adding: "If players that played 90 minutes two days ago were fantastic, I expect people who are not playing a lot to raise the level to create me problems.
"I love problems of choices, and it is easy to choose my team for Saturday."
Asked specifically if Salah and Schurrle had disappointed him, Mourinho replied: "Yes."
