David Sullivan urges West Ham to improve following Bournemouth loss, insisting 'Slaven Bilic, the players and the staff all know we have to do better'

West Ham joint-chairman David Sullivan has warned manager Slaven Bilic that his side needs to improve.

Sullivan voiced his frustration after the Hammers were beaten 3-2 by a Bournemouth side previously without a win in 2017.

Joshua King grabbed a hat-trick, including a last-minute winner, after Michail Antonio opened the scoring for the visitors and Andre Ayew made it 2-2.

And Sullivan has made it clear he wants to see better when West Ham host Leicester next weekend.
