Megan Campbell came off the bench as Manchester City began their Women's Champions League campaign with a thrashing of Swiss side Lugano 7-1 in the first leg of their round of 32 tie.

City dominated at the Cornaredo Stadium but were remarkably being held 1-1 at the interval.

They took the lead through Georgia Stanway and hit the woodwork twice but Kaela Lee Dickerman equalised against the run of play just before the break.

Aoife Mannion restored City's lead from the penalty spot after 48 minutes and the visitors then took firm control with a well-taken Pauline Bremer double.

Three more goals came in the final seven minutes with Caroline Weir twice on target, either side of a Janine Beckie effort.

Campbell replaced Gemma Bonner in the 70th minute. The defender has endured an awful couple of years with injuries but she penned a fresh deal at the Etihad in June and got some welcome minutes under her belt tonight.

Her Republic of Ireland team-mates Katie McCabe and Louise Quinn both played their part as Arsenal cruised to a 4-0 win at Fiorentina.

The Gunners were in fine goalscoring touch at the Stadio Artemio Franchi, where they were playing their first European fixture in more than five years.

Vivianne Miedema opened the scoring after 18 minutes and set up Kim Little to double the lead before the break.

Miedema pounced on a poor backpass to claim her second after 51 minutes and Lisa Evans completed the scoring with a powerful volley. 

McCabe played the full 90 in Italy, with Quinn coming on for Viktoria Schnaderbeck on 76 minutes. Tyler Toland, who scored for Ireland in their 2-0 defeat of Montenegro last week, was on the City bench.
