UEFA Women's Champions League live streaming: Preview

This week, the knockout stage of the Women's Champions League starts. Both Chelsea and Arsenal want to be the first English team to win the trophy since the Gunners in 2007.

The tournament was still called the UEFA Women's Cup back when Arsenal beat Umea of Sweden in the final. 

It wasn't called the Champions League until 2009, and there wasn't a group stage until last season.

This season, Chelsea and Arsenal showed how strong the English Women's Super League is getting by cruising to the top of their groups.

For example, the Gunners beat the reigning European champion Lyon 5-1 away in France. Arsenal beat Chelsea 3-1 earlier this month to win the English League Cup. 

This week, Arsenal plays Bayern Munich and hopes to avoid losing in the quarterfinals for the second straight season to a German team. Last season, Arsenal ended up losing to Wolfsburg.



Bayern is currently two points behind Wolfsburg, which is in first place in the Frauen Bundesliga.

Chelsea, on the other hand, is going to France to play a Lyon team that has won the Champions League a record eight times, including six of the last seven years.

Arsenal is five points behind the leading in fourth in the WSL, while London is two points ahead of Manchester United and Manchester City with a game in hand.

Last season, Barcelona almost won the title again. They made it back to the final, but lost to Lyon in Turin.

Even though Ballon d'Or winner Alexia Putellas is still hurt, it continues to beat all of its opponents in Spain and is now in the quarterfinals, where it will play Roma.

"Barcelona's numbers are crazy and unbelievable," said Alessandro Spugna, the coach of Roma. "I've watched Barcelona a lot, and the more I watch them, the fewer flaws I see."
