Allardyce knows today's home clash with Arsenal will see an end to their smooth run.
Big Sam said: "We have 11 points from six games so we are delighted that our start has been as fruitful as it has been.
"Arsenal are a top four side. This is a big test for the players and whether they can master the quality of opposition.
"Can they understand what they need to do to get the best chance of a result?
"We will have our game plan and hopefully that will get us a result but that means every player playing at their best.
"Even then, it may not be good enough."
