Andre Ayew felt the support of the London Stadium crowd on Saturday, but was disappointed not to reward them with a positive result against Leicester City.
First half goals from Riyad Mahrez, Robert Huth and Jamie Vardy left the Hammers up against it, but Ayew's 63rd minute header - his third strike in the last four games - reduced the deficit to 3-2 and gave this side real hope.
The Hammers continued to knock at the door, but missed opportunities by Ayew and strike partner Andy Carroll kept the Foxes in front to the end.
Aye thought his side had done enough to get something from the game and was impressed by the atmosphere created as his team fought their way back unto the contest.
He explained: "We are very, very disappointed. I think we didn't get into the game when we had to and Leicester scored three goals out of nothing really.
"Two set pieces and once cross have led to the three goals, but we had chances to get back into the game and we didn't. We need to go back, learn from our mistakes and be better for our next game away at Hull.
"There have been games where we have conceded goals in the first ten or 15 minutes and we need to work on that and change it, because conceding early changes the whole game.
"We had positive things, but when you don't win you see them. The fans were behind us the whole game and helped us to push and try to get back into it.
"We had chances and we need to work on our play in the two boxes, offensively and defensively, and hopefully we can start winning games."
