Arsenal 0-4 Barcelona
Barcelona put on a dominant display in a 4-0 Women's Champions League win over Katie McCabe's Arsenal at the Emirates Stadium.
The Gunners were beaten 4-1 by the current European champions in their opening Group C fixture and struggled to improve on that performance, despite recording three successive victories in their subsequent matches in the pool.
Barcelona controlled possession and capitalised on Arsenal's defensive mistakes, with Aitana Bonmati striking the opener before Jennifer Hermoso doubled her side's lead in the 29th minute.
Fridolina Rolfo scored from outside the area for Barca's third in first-half stoppage time, before Hermoso added her second to cap off Barcelona's victory in the 75th minute.
The Catalan side had already qualified for the quarter-finals, with Arsenal needing a win to secure their place in the next round, although they can still do so if they avoid defeat against Hoffenheim in Germany next Wednesday.
Barcelona took a deserved lead in the 22nd minute. Jennifer Beattie tried to find an Arsenal colleague with a pass across her own goal, but the ball lacked power and direction and was quickly intercepted by Bonmati.
The midfielder had a lot to do but worked her way into a good position to be able to put the ball past Manuela Zinsberger in the Arsenal net.
Barcelona had a second six minutes later, when Hermoso guided Rolfo's cross past the home goalkeeper.
Hermoso was unmarked in the middle of the box when the ball came in and, despite Zinsberger managing to get a touch, the ball crept over the line and into the back of the net.
The visitors then added a third just before the break. After winning the ball back on the edge of the box, Rolfo fired home a right-footed effort from distance.
Barcelona finished the first half having enjoyed 74% possession and, just as Arsenal looked to be containing the visitors' threat in the second, the defending champions struck again.
Zinsberger had just made a double save to deny Caroline Graham Hansen and then Hermoso, but she was unable to keep out the latter after Arsenal failed to deal with a low cross, as Barca wrapped up a comfortable victory.

Meanwhile, BK Haecken midfielder Elin Rubensson has called on Swedish football to support players who decide to become pregnant during their elite careers and offer them greater security.
Less than a year after the birth of her son Frans, Sweden international Rubensson was back pulling the strings as her side lost 5-1 to Bayern Munich in the Champions League on a snowy night in Gothenburg on Thursday.
That result ended Haecken's chances of qualifying for the knockout stages, but Rubensson is keen to use her platform to push for change.
"When I became pregnant there was no pregnancy policy. I have a relatively long contract with two years left so I wasn't that worried, but if I had a contract that was running down I would have been worried, because you don't know what is going to happen," she said.
The 28-year-old said players discuss the situation and suggested either freezing contracts or automatically extending them in the event that a player becomes pregnant.
"There is a pregnancy policy being created to provide security so we know what is happening, and (players' union) FIFPro have created one at a European level," Rubensson said.
"The Swedish union is doing the same but they aren't quite finished yet. They've been doing it since I came up to the elite level, and it's very bad that it hasn't been completed yet - it should be given that it is in our contracts."
Capped 70 times by her country, Rubensson was paid 10% of her salary by her club, along with a Swedish social welfare payment paid to those who cannot do physical work during pregnancy.
