Chelsea's first sniff of a chance as a loose defensive pass gives the ball away to Sjoeke Nusken in the area, however her shot lacks power and is easily blocked.

Neither side have had a shot, and Lyon have had one touch in the Chelsea box. Chelsea have had no touches in the home area.

Cagey.

I think Chelsea have done really well in these early stages at staying tight to this Lyon side. But then it's about what's next and playing the right pass.

Chelsea were forced back in the opening five minutes, but have started to get a foot on the ball now.

This is probably their most difficult Champions League group fixture this season. Would they be happy with a draw?

There's no Katie McCabe or Naomi Girma for Chelsea tonight, with McCabe absent having appeared to have suffered a hand injury against old club Arsenal last weekend.

Her absence means Alyssa Thompson is filling in at left wing back, and already the American doesn't look totally comfortable in that unfamiliar role.

A first chance for Lyon, as Caroline Weir whips a dangerous cross towards the near post.

Lucy Bronze stoops to head it behind, before Hannah Hampton is fouled during the Lyon corner.

Jonatan Giraldez was Barcelona manager when they were beaten by Sonia Bompastor's Lyon in the 2022 Champions League final.

Giraldez is in the Lyon dugout tonight, and Bompastor would love a repeat.

Lyon

As the English clubs stuttered through their first games, last season's finalists Lyon made a statement.

The French giants started their Champions League campaign at Servette in Switzerland, where they won 8-0, with Marie-Antoinette Katoto scoring a hat-trick as they racked up 31 shots and hit the woodwork.

Now they're Chelsea's problem.

Away we go at Groupama Stadium.

It is an interesting XI named by Sonia Bompastor tonight - three at the back, Alyssa Thompson at wing back and Lauren James on the bench.

Will her gambles pay off?

Lexi Potter is in the starting XI tonight. Can she boost her burgeoning reputation further?

The players are out on the field in rainy Lyon.

When Sarina Wiegman named her squad for England's upcoming World Cup qualifying matches, one uncapped inclusion caught the eye - Lexi Potter.

The 20-year-old Chelsea midfielder's first senior call-up follows her standout start to the season.

The Chelsea academy graduate broke through last season, scoring the winner on her first WSL start against Brighton in March.

It came after a two-year spell on loan at Crystal Palace where she gained regular first-team football.

This season Potter has stepped up, starting alongside England midfielder Kiera Walsh in three of Chelsea's four WSL matches.

Their partnership is flourishing and it has allowed Walsh to push further up the pitch and provide a goalscoring threat for the Blues.

Potter has shown immense composure on the ball and maintained a 93% passing accuracy in the WSL so far this season.

She ranks fourth among her team-mates in tackles and interceptions and has the third-best passing success rate at Chelsea.

The midfielder has already played 207 minutes, made 21 recoveries in the WSL and is yet to be on the pitch while her side have conceded a goal this term.

It's clear she is making an impact.

A brilliant goal from Wieke Kaptein handed Chelsea victory on their opening night in what was a promising attacking performance from the Blues.

Summer signing Melvine Malard was bright in her pre-planned 45-minute appearance, while Alyssa Thompson's electric display showcased what she could offer in her second season at Stamford Bridge.

With Ellie Carpenter playing behind Thompson, Chelsea's right side could be a potent weapon as they strive to return to the summit of English football - and, in reality, they ought to have added a couple more goals against Austria Vienna.

However, there were concerns for Sonia Bompastor. Shorn of injured captain Erin Cuthbert and with Keira Walsh substituted early, they ceded control in midfield to the Champions League debutants.

Indeed, Vienna came close on a number of occasions to taking a deserved point, hitting the post and having more shots than their esteemed opponents.

Although Chelsea have only conceded one goal in four matches this season, the fragility on display could cost them against more clinical opponents.

Chelsea secured a narrow win over Austria Vienna in their opening Champions League league-phase match.

Wieke Kaptein scored the only goal with a stunning 25-yard strike that went in off the crossbar.

On their debut in the Champions League, Austria Vienna looked capable of delivering a shock as defender Virginia Kirchberger shot over from close range after Chelsea goalkeeper Livia Peng spilled a corner into her path.

In-form midfielder Keira Walsh came off with an injury, however her inclusion in the England squad indicates it may not be too serious.

Right, that penalty will create waves that will ripple on for quite some time - but we must move on, as we are less than 20 minutes away from another massive Champions League game.
