Chelsea booked their place in the Women's Champions League semi-final as Pernille Harder came back to haunt old club Wolfsburg once again.
The Blues edged a narrow first leg encounter 2-1 last week but proved too much for their opponents in the second game held at the Szusza Ferenc Stadium in Budapest.
Harder and Sam Kerr were on target in the first leg and both forwards were involved again as they scored twice in four minutes to take control of the tie before half-time.
Kerr won a penalty in the 27th minute when she was bundled to the ground by Sara Doorsoun-Khajeh.
