West Ham United goalkeeper Robert Green admits it's tough going after conceding 12 goals in the last three games.
Green, 28, said: "It has been a horrific week and everyone will get flak for it. I don't think I've had a week like it in football and the same probably goes for most of the other lads.
"You must keep believing you're doing the right things. Over the last week, I don't think I've had one goal I could have saved.
"It has been very frustrating and you have to look at yourself, along with the rest of the guys, and wonder what else I could be doing for the team. It is a collective thing, not an individual issue. We have to keep our heads and keep going.
"If someone turns to me and says 'You could do this in that situation', I will listen and take it on board.
"It is a case of being professional. We have a hell of a lot to learn from this week.
"I don't think it would help anybody if the fans turned on us. I understand their frustrations and the performances that have been put in. It hurts. Two out of three were against London rivals and that is not what you associate with West Ham United, losing games like this.
"The lads are bitterly disappointed. We played Chelsea and for the last 20 minutes it was in front of a half-empty Upton Park. At White Hart Lane, I looked over at the West Ham fans towards the end. It was half-full - and rightly so.
"People vote with their feet. But hopefully we can go and do something about it during the rest of the season and push on."
