Heinze said: “All defeats are disappointing so we were a little bit down, a bit sad after West Ham.
“But it’s in the past, it’s over. What we must do is learn from the errors we made. We’re still happy we’ve a two point advantage but losing sticks in the throat a bit.
“However, it draws our attention to that run of good victories we had before the defeat.
“What we’ve got to do is concentrate on that same line, get back to winning ways and carry on picking up three points in order to add to that two point advantage.”
