West Ham manager Sam Allardyce has urged his side to reward their fans' loyalty by continuing to improve their home form.
Allardyce's team sit second in the Championship, as they look to secure immediate promotion back to the Premier League. That strong position has been achieved despite their patchy form at Upton Park.
Tonight, they host Derby, with another crowd of around 30,000 expected, and Allardyce is keen to repay their loyalty.
"The support is superb," he said. "It goes without saying that West Ham's supporters are one of the big attractions of the football club.
"Throughout the year, it has a hardcore support, irrespective of what division the team is in. They love the club so much they want to turn up and support it.
"The most important thing is to deliver what they want. They want winning football, they want to go home happy at the weekend, see the team win a game of football and try and win the right way as always.
"We are doing that at the moment. If I can label any criticism at the players regarding the fans, it is that at home we haven't quite delivered for them as well as we have away.
"At home we have had good performances lately, and we want to continue that against Derby and give the supporters what they want. That is to go home and wake up tomorrow delighted to have watched their team win."
