The Rs face Norwich today looking for only their second league win of the season at Loftus Road.
Keeper Cerny said: "Our away form maybe is better as pitches like these are bigger than our home pitch.
"We tried to play football. At home it's more difficult. We have to play more direct but we will try to change that in the next game. A couple of weeks ago we looked at the fixtures and saw some really difficult games ahead.
"Now we must hope we've got easier games and after New Year we must grab some points.
"The next two months are so important for us. The end of the season will be very difficult and we must make sure we have built up some good form and points."
