Davey, whose side face three consecutive home games against Birmingham, Blackpool and Crystal Palace, said: "We now have three massive home matches this week. It is no coincidence that we tend to win games here when our supporters are right behind the team.
"We get results when we are together and we showed that against QPR. We have three matches in a week that will shape our season.
"Birmingham will come here with an arrogance about them because they are going for promotion. They will expect to come and win this game and attack us. Hopefully that will benefit us."
