Allardyce said: "The fans have become a bit spoilt because of what we have achieved.
"However, we are facing a big test for the first time this year.
"The players did magnificently to get so many points in the first 10 games, but now we are having a blip.
"The next two away games are massive but even more difficult than normal.
"We have to get back to the basics, do them correctly and play our normal game.
"We have won the last three away matches, so we can go into the game with confidence."
