Sections of the Upton Park crowd voiced their frustration at the end of each half after a lacklustre display from the promotion favourites.
"As a manager you have to take it but one or two of the players in the dressing room were a little disappointed to get booed because we are at the top of the league," revealed Hammers boss Allardyce.
"You build up the expectation as we have done recently having done so well, and we didn't deliver. But the fans have to stay with us and have to be patient, and then we'll all benefit in the end.
"I told the lads we are all disappointed and the fans are showing their disappointment.
"They cheer us when we win and they were not so happy we didn't play well, but that's the way it goes."
