West Ham boss David Moyes says they won't underestimate Burnley.
Moyes feels Vincent Kompany is doing well as manager with the struggling Clarets.
He said, "I have sympathy for a lot of managers.
"He's done a really good job with what he has got. He did a brilliant job last season and has continued to bring them on.
"His team have played well in many games this season and we will need to play really well to beat them."
