AC Milan confirmed their place in the Europa League's last 16 with a comfortable 1-0 victory (4-0 on aggregate) over Bulgarian side Ludogorets at the San Siro on Thursday.
Former Liverpool and Sunderland striker Fabio Borini slid in Patrick Cutrone's cross to open the scoring for the Rossoneri in the 21st minute.
In the second half, the visitors pressed for an equaliser but Swierczok wasted their best opportunity of the game when he shot straight at Donnarumma from 10 yards out.
The impressive Cutrone should have put the game to bed when Borini's shot found him at the far post, but the youngster poked his effort just wide of the goal, before Milan saw out the remaining half an hour with relative ease.
