Premier League champions at Upton Park on Saturday.
Big Sam was critical of his side’s performance against Wigan and admitted the Hammers didn’t deserve to win.
“I was surprised at our performance and it was the kind of performance that you know you’ve got to avoid when you’re a newly-promoted side playing away from home.
“When you play at this level and you want to win a game away from home you’ve got to play to your best. We didn’t do that on Saturday at any time at all really.”
However, the former Bolton and Newcastle boss still has faith in West Ham’s ability to play good football.
“The one thing that has got us where we are is that our technique has been very good in possession, which has kept the pressure off us at home and away from home, which is how we’ve managed to get results that perhaps people didn’t expect us to.”
Andy Carroll has been an integral part of West Ham’s attack this season, despite not yet netting a single Premier League goal. Allardyce believes the striker is given a tough time by Premier League officials.
“He doesn’t get given enough free-kicks as he gets manhandled by defenders struggling to handle the quality that he’s got. They don’t seem to give the free-kicks that they would perhaps give against shorter players. Andy knows all that, so he’s just got to be patient with it” said the Hammers manager.
Following West Ham’s clash with the league champions, the East Londoners face a tough run of fixtures, taking on Newcastle, Manchester United, Tottenham, Stoke, Chelsea and Liverpool over the next six weeks.
