West Ham co-chairman David Sullivan insists manager Slaven Bilic and his side must improve following their 3-2 defeat at Bournemouth.
Sullivan expressed his frustration after West Ham produced a below-par performance at the Vitality Stadium on Saturday, which left the Hammers without a win in four matches.
Josh King netted a hat-trick, including a 90th-minute winner, to secure Bournemouth's first victory of 2017 after he and Benik Afobe had both missed from the penalty spot.
Michail Antonio opened the scoring for West Ham and Andre Ayew had made it 2-2 with less than seven minutes remaining before King grabbed the decisive goal.
West Ham welcome a revitalised Leicester side to London Stadium on Saturday and Sullivan is expecting a response from Bilic and his players.
"I was very disappointed and frustrated with the manner of our defeat at Bournemouth on Saturday," Sullivan told the club's official website.
"We went down there determined to bounce back from the Chelsea defeat on Monday, but we didn't play as well as we know we can.
"Slaven, the players and the staff all know we have to do better.
"We have conceded too many goals early in halves in recent games and, while we've managed to get ourselves back into games like the ones at Southampton and Watford and at home to West Brom, there will be matches where we cannot equalise. That situation cannot go on.
"I am sure that Slaven, his backroom staff and the team were not happy with what happened and they will think about it a lot over the next few days."
