LONDON, March 25 — Stina Blackstenius, Chloe Kelly and Alessia Russo were all on target as Arsenal beat Chelsea 3-1 at the Emirates Stadium yesterday in the first leg of an all-London women’s Champions League quarter-final.

Lauren James pulled a goal back for Chelsea to keep the Blues in the tie but reigning European champions Arsenal will still be well-placed come kick-off in next week’s second leg at Stamford Bridge.
