David Sullivan has apologised to West Ham's fans following the 3-2 defeat at home to Leicester.
The Hammers' joint-chairman gave manager Slaven Bilic a stark warning last week, following the 3-2 loss at Bournemouth, that they had to stop conceding early goals.
It seems the message did not get through, though, as they found themselves 2-0 down after just seven minutes.
Sullivan now admits West Ham's next three games are 'vital' as they try to arrest their slide.
