Courtois told Chelsea TV: "We win our games and then it's really hard for other teams to see that the team that's top of the table still keeps winning games. That really sends a message.
"It will be a hard week and we hope to have the maximum points."
Courtois made a number of saves against Hull as he recorded a 13th Premier League clean sheet of the season.
"If we keep clean sheets we can win our games and that's the most important (thing)," the Belgium keeper added.
