Wilshere joined Aarhus on a short-term contract in February after going months without a club.
The 30-year-old made his debut as Arhus lost 3-2 to Vejle in the league last week and has described his new club’s fans as the best he has seen.
“It was a proper debut,” Wilshere told talkSPORT. “It was end-to-end and was 2-2. It was the worst pitch I’ve ever seen.
“Then, halfway through the second half, bang… the floodlights go out.
“Everyone went back into the dressing room, there was a 15 or 16-minute delay and then back out.
“When I came on [in the 90th minute] there was still 15 minutes added on.
“It was really about 72 minutes [when I came on]. They scored a set piece and as you know… I’m average height… but they are quite tall over here and I can’t do much on set pieces.”
He continued: “We played bottom of the league and the conditions over here have been bad. We’ve had a storm and it’s been raining ever since.
“It was the same on Friday night. We played against a team who just didn’t play. Every time they got the ball from the back and they were going long.
“We kind of got sucked into playing that way, and that’s not the way we play.
“We still should have won the game.”
Wilshere said: “Our fans, I will say they are the best I’ve ever seen. In the warm up they were there singing right from the warm-up.
“They had 2,500 fans there.
“We’ve got four more games left and then the league gets split in half and you play in the mini-league.
“The top half for Europe and the bottom for relegation. We’ve got four games to get in the top six and we’re going to do it.”
