West Ham boss David Moyes has appealed to supporters to get behind the club ahead of Friday's clash with Leicester City.
During the defeat at Watford last Sunday, West Ham's travelling supporters chanted for the board to be sacked and also aired a chant of 'you're not fit to wear the shirt' after the team went 2-0 down.
West Ham remain rooted in the relegation zone after 12 matches of the Premier League season.
Moyes said: "I want everybody to be together and be united and help each other along.
"I'm not aware of any problems before I came, I wasn't made aware of anything. I was a little bit surprised when I heard it, I've got to say.
"I want them behind us, I want to give the team every chance of winning.
"West Ham have always been a really vocal support, I can vouch for that over the years."
He added: "For years and years I came and you're always looking forward to getting away from Upton Park after the game because you knew it was going to be tough so we want them to be supportive of the team.
"They are knowledgeable supporters, they've seen a lot of good stuff going on over the years here and they will be wanting the team to be playing well.
"I've said many times you've got to be all together and make sure whatever happens and what is said outside is affecting us all, not just one."
