Over 5,000 DIF fans are in London for the second-leg of their Europa Conference League semifinal. Chelsea hold a 4-1 aggregate lead.
Jorgensen told Fotbollskanalen: "It's a fantastic match, a semi-final in Europe. They still think they can turn this around. We are very focused on doing the job and getting another win. Nothing is done.
"We take this one seriously just like other matches.
"I don't think anyone (at Chelsea) thinks this is over. There are 90 minutes left to play and we will give it our all. We want to win this match too."
Everything is up to the coach
Jörgensen has not had much playing time in the Premier League so far, having only made six appearances. The 23-year-old has played more in the various cups.
He added, "I just try to do my best every day and show that I want to be number one. Just like everyone else. I do my best and then it's up to the coach (Enzo Maresca)."
