Janelt told the club's website: We're disappointed.
We put a great shift in and had a really big chance for Nathan (Collins) from a cross from (Kristoffer) Ajer. It was a big chance to score to lead 2-1. It was a great shift, but we didn't get the points.
Right now, I don't think momentum is with us. Everyone expected that Arsenal would win by three, four, five today because of their last results, but everyone knows how difficult it is to play against us either at home or away."
Janelt added: They didn't create many chances and, for me, it was a clear yellow and then red to Havertz; it was a clear dive for me. Then he scores the winner, but that's football.
The goal for Wissa shows how hard we work - we never stop. Arsenal away, we still pressed them high and tried everything to score."
