Chelsea v Barcelona LIVE: Barcelona go ahead in the tie with one goal in each half, Chelsea down to ten players

But gets the ball out and finds a blue shirt. Chelsea weathering the yellow storm so far.

Nothing doing from the referee. Did look very soft.

Beautiful footwork from the right winger.

Patricia Guijarro's touch is too heavy and it's out for a goal kick.

Jess Carter does well to get in front but can't prevent the first corner of the game.

Chelsea looking as alert at the back in these opening minutes as they were a week ago.

Catarina Macario looks to thread one through for Lauren James, but there's just a little too much on it.

Bonmati getting her hustle on early doors.

Lauren James immediately knocks the ball forward, and it quickly goes out of play for a Barcelona throw-in. The Catalans are playing in yellow.

The first Stamford Bridge sell-out and it feels like Chelsea's entire season has been leading up to this moment. The magnitude of the occasion has not been lost on the players. Captain Niamh Charles has called this "the biggest match they will play in their careers." Unless they get through to the final in Bilbao. Emma Hayes said her women will have to play "the perfect game."

The players are out, the anthem is playing all around the stadium. The bookies have Barcelona as favourites to go through but Chelsea have upset the odds before, and they're keen to do it again.

Just the one change to last weekend’s teams that faced each other. For Chelsea Maya Ramirez, such a lively, vibrant force last weekend is unavailable, so Catarina Macario comes into the side as a like-for-like replacement.

Emma Hayes has switched from a back three to a defensive line of four, comprised of Ashley Lawrence, Jess Carter, Kadeisha Buchanan and captain Niamh Charles.

Jonatan Giráldez for his part has benched Mariona Caldentey and brought in England full-back Lucy Bronze for what could be one of the Lioness’ last games in the red and blue. She’s out of contract in the summer.
