The 20-year-old front-man is attracting attention from a host of Premier League clubs, and the Danish media claim Arsenal, Tottenham and Stoke City all deployed scouts to check on him during the match with the Czech Republic.
"First of all, we are happy on Cornelius' behalf," stated sports director Carsten V. Jensen to Sporten.dk after he scored the opening goal in Friday's 3-0 win.
"I am particularly happy how he handles the situation around him. It's not easy to keep your focus on your displays when you get a lot of attention."
The Danish giants are hoping to qualify for the group stage of the UEFA Champions League after the summer and therefore the club have no plans to sell their talented striker.
"Selling players is not in our plans." he added.
"We are in a phase where both the side and individual players are making progress and the most important thing for us is to prepare the club for the challenges which hopefully will come."
