MADRID - Chelsea were held to a goalless stalemate by Hacken in the Women's Champions League on Tuesday, while Real Madrid notched up a first win.

The English club hit the woodwork twice in Sweden as an inspired showing by Hacken goalkeeper Jennifer Falk also helped keep the visitors at bay.

Chelsea go outright second in the league phase table after four matches, one point behind defending champions Barcelona, although the perfect Catalans hold a game in hand.

However, several teams, including Lyon and Arsenal -- both of whom are just a point behind Sonia Bompastor's side -- could leapfrog them this matchday.

In the Spanish capital, Real Madrid downed visitors Paris FC 3-0 thanks to three second-half strikes.

A first win of the league phase sent Pau Quesada's side sixth in the table on six points, while Paris FC lounge 15th on two points.

Arianna Caruso broke the deadlock in the 55th minute.

The hosts' lead was doubled 10 minutes later as Dutch forward Lineth Beerensteyn thumped home.

Linda Caicedo made the points safe with nine minutes remaining as she finished smartly from Felicia Schroeder's reverse pass.

Swedish attacker Schroeder laid on all three goals in a sparkling performance by the 19-year-old.

Later, Manchester City visit Inter Milan, Roma host Servette and Paris Saint-Germain welcome Bayern Munich.
