Chelsea manager Emma Hayes said it was "a job half-done" after her side gained a crucial Champions League first leg win over holders Lyon.
The in-form Guro Reiten got the goal in the 28th minute to secure a 1-0 quarter-final victory, against a side who have dominated women's European football for the best part of the previous decade. But Lyon have been more vulnerable this season, Arsenal beating them 5-1 in the group stage, and Chelsea were good value for their win.
Despite this Hayes said she was initially "frustrated" with her team after their start to the game and said they needed the goal to settle them down. The Blues will now host Lyon in the return leg next Thursday knowing a draw will be enough to take them back to the last four of the Champions League.
