Sam Kerr scored four goals as Chelsea crushed Vllaznia 8-0 in the Women's Champions League on Wednesday, maintaining their perfect start in Group A.

Pernille Harder also struck a hat-trick and Katerina Svitkova headed home late on as the Blues followed up last week's impressive win over Paris Saint-Germain with a dominant display at Kingsmeadow.

Kerr needed just an hour to hit the net four times, finishing from close range on three occasions as well as converting Guro Reiten's corner with a towering header. 

Chelsea now hold a two-point advantage at the top of their group after Real Madrid played out a lively 0-0 draw with Paris Saint-Germain at the Estadio Alfredo Di Stefano.

In Group B, Wolfsburg recorded their second win in as many games as goals from Jule Brand and Ewa Pajor helped them to a 2-0 success against Slavia Prague.

However, the two-time Champions League winners look set to be pushed all the way by tournament debutants Roma after they triumphed 4-3 in a remarkable meeting with St. Polten.

Alessandro Spugna's Giallorosse were 2-0 down with 15 minutes to play, but held firm after goals from Elena Linari, Valentina Giacinti, Manuela Giugliano and Paloma Lazaro turned the contest around to move onto six points.
