West Ham manager Manuel Pellegrini: "I don't know if it was an unacceptable performance. We conceded the first goal from a corner that was not a corner.
"When you concede so many easy goals, it does not help. I am concerned at the easy goals we are conceding. We need to change.
"We have 15 days and we will try to recover. The international break has come at a good time. We need to work hard and reverse this situation. It's more than just confidence - we are conceding too many goals. if you concede too many easy goals, it is very difficult to win."
On the injury to Manuel Lanzini: "We will see what has happened with his shoulder but he will probably be out for some time."
Burnley boss Sean Dyche: "We were off the mark last week. From the very beginning of the game today our body language, intent and belief was there.
"Dwight McNeil had a tough game last week but he bounced back with a really good performance. I told him this week I'd kick him somewhere if he didn't smile more!
"We have picked up six points from the past five games. It doesn't sound much but when you see the teams we have played then it's not a bad return.
"People forget we had one bad game last week - we've actually been going along well this season."
