Brendan Rodgers has admitted that he is "disappointed" by Liverpool's loss to West Ham United at Anfield in the Premier League.
The Reds fell behind early on and had Philippe Coutinho sent off on their way to a 3-0 defeat, ending their unbeaten start to the campaign.
The manager told BBC Sport: "The first goal is a cheap goal and that gave them a motivation and fight. The second was a mistake, which can happen. We started brightly and then had Coutinho sent off. I didn't think that was a sending off and neither was the one for Noble as well.
"We didn't defend moments well at all. We need to be much better than that. That opportunity to work the goalkeeper didn't happen. We are disappointed but we'll reflect on it and come back and look to win our next game."
Liverpool travel to Old Trafford to face Manchester United after the international break.
