Simons laid on one assist in the 4-0 win.
He later said, "It was really important to bounce back from last weekend and come here in front of the fans and win the three points. That was the most important thing.
"Of course (I'm enjoying being here). I'm in a new place and for the first time it has been a little bit hard for me. I am a guy who will never let my head drop. I will keep working, nobody will keep me on the ground. I know what I can bring to the team so I will keep working hard and things will come, 100%.
"We have to enjoy this tonight and tomorrow we go back and watch the game then focus on the next (matches)."
Meanwhile, manager Thomas Frank said of Simons: "I will say two things. One, I think that was a step forward today. I'm very happy for him. I think it was a good assist and I agree with you. A little bit more sharpness for him and the other players. I think he probably had one more assist.
"I think he found good pockets, good spaces. I'm really pleased with that. Of course, I understand his disappointment (being substitued) in the moment. But it's always about the team, of course. At that stage, it's 2-0.
"We are still building layers in this team. I think it's obvious that we are progressing forward but are not where we want to be. In that situation, we just take no risk and put a more defensive player in. Which afterwards, of course, looks to be an absolutely top decision. But you never know."
