Horsham boss Dominic Di Paola says they must take the rough with the smooth this season.
The Hornets manager conceded it was one of those days after they exited the FA Vase on Saturday.
A Lee Garnham header on 117 minutes gave their local rivals Steyning Town a place in the second round after the game finished 0-0 after 90 minutes.
Di Paola, although pointing to the pitch as a leveller, refused to make excuses and said they will take the criticism.
He said: “I have done a bit of soul searching this week, you do when you lose, I do when we win as well.
“We knew it was going to be hard this year, it’s a cup final for the opponents in every game, you do not get big clubs like Horsham in this league very often.
“There are no expectations on us that we did not deserve. The fans clapped us off on Saturday, but had every right to boo us off the pitch.
“People have every right to be critical. If you take the credit, you have to take the criticism as well, it can’t just be pats on the back, there is the other side of it.
“It was one of those games when nothing really went or fell for us, there was not much more we could have done. The players were really disappointed and I am sure they will be in the right frame of mind this weekend.
“I have never been on the end of giant killing, so it’s a first for me in my managerial career, there have been a few firsts this year, but they just had their day and you have to congratulate them.”
