Chelsea found the free-flowing rhythm that has previously eluded defeat of Albanian champions Vllaznia in the Champions League.
Four goals from Sam Kerr, three from Pernille Harder, one from the substitute Katerina Svitkova and four assists from Guro Reiten on her 100th Chelsea appearance, helped the Blues take control of Group A with Real Madrid and Paris Saint-Germain having drawn 0-0 in the earlier fixture.
