Delac, 27, now plays for AC Horsens and is preparing for Monday's first game back against FC Midtjylland - in an empty stadium.
"It's a little strange, but we tried it in the Park, and it's an advantage for us. As a goalkeeper, I can communicate much better with the players in front of me," Delac told
"The physical has not been a problem, but everything else has demanded something more, and the biggest challenge is definitely the mental one. It's probably going to require a couple of matches before I'm at 100 percent."
