FC Copenhagen boss Jacob Neestrup has sent a warning to Manchester United ahead of their Champions League tie against the Danish giants on Wednesday.
The two teams face off again in the group stage after a dramatic clash last month when Andre Onana saved Jordan Larsson's last-gasp penalty to give United a crucial 1-0 victory through Harry Maguire's goal.
It is a huge game for Erik ten Hag's side, who are playing catch-up after losing their first two games of the competition to Bayern Munich and Galatasaray, with the Red Devils needing to win in Denmark.
