AC Milan's hunt for the only European title they lack will continue against Ludogorets Razgrad in the last 32 of the Europa League.
With Milan currently seventh in Serie A, the Champions League place awarded to the Europa League winners could be the best chance for the seven-time European champions to return to the elite competition.
AtlEtico Madrid, 2010 and 2012 Europa League winners, were drawn to face Copenhagen after placing third in their Champions League group. Napoli will play Leipzig in a pairing of two more teams, which dropped down from the Champions League.
Also, it was: Celtic vs. Zenit St Petersburg; Ostersund vs Arsenal; and Astana vs Sporting Lisbon.
The first legs will be played on February 15, with the return games on February 22.
