The Clarets won 2-0 on Saturday, leaving Farke frustrated - though realistic - with the result.
"In football, the only thing that is important for the result are goals and this was missing today,” the German began.
“So, missed an unbelievable amount of big chances as well and not just shots or strikes but also big chances. Must have been four or five times more than them in terms of expected goals.
“If you have one of these days when you can’t bring the ball over the line, then you have to be perfect, of course, in defending.
“We defended well, we didn’t allow much but one situation before half-time. A bit annoyed with the goal we conceded in the first half because of course quality cross from Kyle Walker and a really good header.
“But (we) should have defended the situation in the centre so it was relatively easy also to defend the header. Not happy with this and also like to block the cross, we also had to be a bit more switched on.
“In the second half, the goal struck out of 25 yards, wonder strike, crazy curve of the ball but yes (we) could have stepped out a bit earlier.
“We have shown several times that we have this mentality where we also can come back and turn games and equalise. Like Wolves, for example, to come back.
“Or Bournemouth, we have done this. But if you always have to climb a mountain, especially in an away game, it is difficult.”
