Barcelona seized control of Group D in the Women's Champions League by thrashing Bayern Munich 3-0 in front of a crowd of 46,967 – a new group-stage record.
Second-half goals from Geyse, Aitana Bonmati and Claudia Pina helped Jonatan Giraldez's team maintain their perfect record in the competition on Thursday, as well as ending that of Bayern.
The Camp Nou crowd – which surpassed the competition's previous group-stage record of 18,341 by a considerable margin – had to remain patient for the opener, but the Blaugrana were good value for their win after Brazil international Geyse broke the deadlock.
The result moved Barca three points clear of their opponents as well as maintaining their six-point advantage over Benfica, who beat Rosengard 1-0 courtesy of Cloe Lacasse's goal.
Meanwhile, Arsenal maintained their narrow lead at the top of Group C with a 1-1 draw against Juventus, who remain two points behind the Gunners after surrendering a second-half lead.
Lineth Beerensteyn put the hosts ahead shortly after the break, but fellow Netherlands international Vivianne Miedema nodded home from a corner nine minutes later to keep the visitors top.
Reigning champions Lyon also remain in fierce contention for a quarter-final spot after cruising to a 3-0 win at Zurich, moving them to within a point of second-placed Juve.
Signe Bruun added two goals after Melvine Malard headed in an early opener, helping the eight-time champions to their first Champions League win of the season.
