The BVB ace was shown up by Robert Lewandowski in yesterday's defeat to Bayern.
But Flick still had some nice words for the youngster, stating: "If Erling Braut Haaland can take over from Robert Lewandowski? Many, many things are possible in life, nothing can be ruled out.
"But we are still far from the mark. He has a long-term contract at Dortmund and is an option for many top clubs."
