Salma Paralluelo scored the only goal of the game as Barcelona edged Roma 1-0 at the Stadio Olimpico in the quarter-finals of the Women's Champions League.

The 19-year-old curled a left-footed effort from outside the box to beat Camelia Ceasar after 34 minutes, after the Roma goalkeeper had frustrated the visitors with a number of fine saves.

Last season's runners-up could not extend their advantage in the second half, while Roma failed to convert a number of chances in the latter stages to pull the tie level.

Elsewhere, Arsenal were frustrated at Allianz Arena by Bayern Munich and suffered a 1-0 loss despite dominating proceedings.

The Gunners saw efforts from Stina Blackstenius and Leah Williamson cleared off the line as they peppered the hosts' goal with 25 shots – though only six were on target.

Lea Schuller's 39th-minute header proved decisive, with Jonas Eidevall's side needing a turnaround in the second leg if they are to reach the semi-finals for the first time in a decade.
