The Gunners won 2-0 via goals from Ethan Nwaneri and Bukayo Saka.
“It’s a strange feeling not being in next round,” admitted Hurzeler. “You don’t usually get as many chances in a game against Arsenal so you have to score the goals and if you do that you are in the next round.
"We had several shots but couldn’t score so that is frustrating. Their first goal changed the game – it’s not easier to score goals here.
“It is a missed opportunity. It’s a game of results and we have to deliver those so now we have to analyse why we didn’t do that in the last two games.
“Even in second half we had some good possibilities to score so we now have to give the players the right support to make sure they do it better next time.
“We have to take the positives and there were plenty of those. The nice thing is that we have our third game in a week in three days when we will try to do better against Leeds. That is our focus now.”
