Jose Fonte apologised to supporters after West Ham United were beaten 3-0 by Brighton and Hove Albion on Friday.
Two Glenn Murray strikes either side of Jose Izquierdo’s long-range curler sealed the points for Chris Hughton’s men during a disappointing night for the Hammers.
Manuel Lanzini and Chicharito had the hosts’ best opportunities in the first half, but the visitors defended well to grab their first ever Premier League win on the road.
Portugal international Fonte was left gutted at the full time whistle and assured fans the side will do everything they can to turn things around.
“We are all disappointed, we are all frustrated and we apologise,” the centre-back said. “It was not the performance we wanted to produce and it wasn’t the performance the fans deserve.
“We need to look at ourselves in the mirror because this cannot happen. It happened a few times last season, and we have to put this right. This is West Ham and it’s just not possible [to let this happen].
“We have got to move on. We have a game Wednesday and we need to go and beat Spurs because we have to react, we have to bounce back.”

And with Slaven Bilic’s side pushing for an equaliser for the majority of the remainder of the opening period, Brighton hit them on the break and doubled their lead spectacularly with Izquierdo’s strike.
Murray grabbed his second from the penalty spot after Pablo Zabaleta had fouled the forward and Fonte admitted all three goals were hard to accept.
“The first goal, from the set piece, when we didn’t do anything was difficult to take,” he continued. “We had a lot of possession but we couldn’t create and it’s disappointing.
“I’m not going to say it is unacceptable because the players, we tried hard. We tried the best we could. It just didn’t go our way. The second goal was a great shot from outside the box and we go into the break 2-0 down.
“Second half, we came with the mentality of getting the goal back and trying to get back into the game and the only occasion they came [forward] in the second half, they got a penalty.
“The fans don’t like to lose 3-0 at home, we don’t like to either. We are going to work very hard on the training ground to not let them down again like this.
“Of course we have to look at ourselves in the mirror. Everyone needs to work hard and we need to bounce back.”
