Nico Williams scored his third and fourth Europa League goals of the season to send Athletic Bilbao through
Nico Williams scored twice as Athletic Bilbao beat 10-man Roma to book their place in the Europa League quarter-finals.
The Italian side led 2-1 from the first leg but had Mats Hummels sent off for a professional foul in the 11th minute - and the hosts made the extra man count.
Williams levelled the tie with a close-range effort on the stroke of half-time and left-back Yuri Berchiche's glancing header from a corner put them in front on aggregate midway through the second half.
A dinked finish at the end of a jinking run from Williams with eight minutes left all but confirmed Athletic's place in the last eight.
However, there were still some late nerves when Leandro Paredes thumped in a late penalty for Roma.
But Claudio Ranieri's were unable to score again to force extra time, as Athletic held on to win 3-1 on the night and progress 4-3 on aggregate.
Athletic will face either Rangers or Fenerbahce in the last eight as they continue the journey they hope will end back at their home ground, San Mames, where this year's final will be held.
