Republic of Ireland international Katie McCabe was introduced as a late substitute as holders Arsenal got their Women's Champions League campaign up and running with a hard-fought 2-0 win over Benfica in Lisbon.
After a low-key first half, Arsenal - beaten by Lyon in their opening fixture of the new-look league phase - went ahead through a scrappy goal from Beth Mead just before the hour.
The Gunners - having ended a four-match winless run with victory over Brighton in the Women's Super League on Sunday - made sure of three points when Alessia Russo slotted in from a well-worked free-kick by substitute Chloe Kelly.
McCabe, on course to become an international centurion in UEFA Nations League promotion/relegation play-off against Belgium later this month, replaced Emily Fox in the 85th minute at Estadio da Luz.
Manchester United overcame the first-half dismissal of defender Dominique Janssen to close out a 1-0 win over Atletico Madrid and maintain their perfect start to the new Champions League campaign.
Sweden forward Fridolina Rolfo fired in a close-range volley to give the visitors a 24th-minute lead.
Netherlands centre-back Janssen was then shown a red card before the break following a VAR review into her sliding challenge on Gio Garbelini, who was taken off on a stretcher.
Atletico also finished the match with 10 players after defender Alexia Fernandez collected a second yellow card with 15 minutes left.
Elsewhere Lea Schuller struck a 95th-minute winner as Bayern Munich edged out Juventus 2-1 at FC Bayern Campus.
Juventus quickly cancelled out Pernille Harder's 11-th minute opener with a superb free-kick from Eva Schatzer and appeared to be leaving with a point before the game was settled by late drama.
Juventus player’s protested that the match-winner should not stand as it was cleared off the line, but despite VAR intervention, the goal stood.
First-half goals from Naomie Feller and Alba Redondo paved the way for Real Madrid's 2-1 victory away to Paris Saint-Germain.
The Parisians pulled one back through Rasheedat Ajibade in the 58th minute, but couldn’t prevent the Spanish club from making it two wins from two in the competition.
