Scotland forward Caroline Weir struck twice as Real Madrid launched their Champions League campaign with a 6-2 statement win over Roma.
Weir was on target in each half at Estadio Alfredo Di Stéfano but it was her first strike in the 23rd minute that set pulses racing as she dribbled into the box before beating goalkeeper Rachele Baldi with a powerful shot.
Madrid went in at halftime 3-2 up but pulled cleared with Weir, their captain, adding her second before Alba Redondo completed her double, with Eva Navarro sealing a dominant victory in which they had 14 shots on target.
Strikers Evelyne Viens and Emilie Haavi netted for Roma, who opened their Serie A Women season with a 4-0 rout of Parma on Saturday.

They had to wait until the closing moments for their next goals, however, with Fiamma Benitez hitting the target twice, the first from the penalty spot.
