Arsenal take first leg advantage over Chelsea in the Women's Champions League quarters
Lauren James managed to score a consolation goal for Chelsea, which keeps the Blues alive in the contest, yet the defending European champions Arsenal remain in a strong position ahead of the return fixture at Stamford Bridge next week.
The Women's Champions League stands as the sole major honour that escaped Chelsea throughout Emma Hayes' decorated 12-year tenure, and the team continues its pursuit of a first European triumph following Sonia Bompastor's appointment in 2024 to replace the coach now leading the United States squad.
Chelsea found themselves thwarted by the frame of the goal on two occasions right at the beginning of Tuesday's encounter.
In the opening five minutes, a delivery from Alyssa Thompson deflected off Laia Codina's foot, arcing over custodian Anneke Borbe prior to striking the distant upright.
Just two minutes afterwards, James watched her attempt strike the identical post before the sphere cleared away.
Arsenal seized the initiative in the 22nd minute as Swedish forward Blackstenius nodded in her inaugural Champions League strike this campaign from a set-piece by Katie McCabe.
The Gunners extended their advantage ten minutes subsequently, with Beth Mead sending a diagonal ball to Kelly, who settled the touch then rifled a 20-yard effort beneath fellow England keeper Hannah Hampton of the Blues.
Chelsea believed they had equalised five minutes prior to the interval, although Veerle Buurman's attempt got chalked off due to a push on Laia Codina, a close call confirmed by VAR that clearly irked Bompastor.
The Blues earned a route back into proceedings in the 66th minute courtesy of James unleashing a stunning left-footed arcing effort from around 25 yards.
However, Russo re-established Arsenal's two-goal buffer 14 minutes before the end, receiving a pass from Blackstenius before lifting the ball and smashing a volley beyond Hampton with elegance.
Chelsea endured further irritation during added time as Kadeisha Buchanan forced the ball over the line, only for officials to award a free-kick against her for a challenge on Borbe.
The teams reconvene on Thursday April 2, where the victors will face either Wolfsburg or the eight-time champions Lyon, the Germans holding a 1-0 edge from their initial clash.
