He believes they must be at their best when they entertain fellow strugglers Nottingham Forest at Goodison Park on Sunday.
We can't just park it - that's for sure," said Dyche about the result against Chelsea.
We certainly haven't. Players were affected by it, and they were very disappointed. As was I, in my part as manager, as well. I take responsibility.
We spoke to the players about it, and they fed back their disappointment, as well as mine. But equally, by now we've made sense of it, of course. But, the day after, we certainly didn't. It was a challenge.
There were a lot of home truths - me included, by the way, about what I expect from myself, from the staff, and from the players, and realigning, saying: 'Right, you can only do it as a group. You can't do it as individuals'.
The players have been disappointed. I must make that clear. It's a funny thing about football nowadays, (people asking) 'Do they care?' They care. Trust me, they care. I care deeply about what we're trying to achieve here.
We've had a chat about it this morning to finish it off and go: 'Right, that's gone. We move forwards.'"
