Manchester City fired out a strong signal of their potential to go deep into the Women’s Champions League this season as they stunned the holders Barcelona with a world-class performance to win their opening group-stage game.

On a night when the technical standard of both teams’ football was a joy to watch, a goal in each half from Naomi Layzell and Khadija Shaw gave the English side a memorable victory that will go down in the club’s history as one of their greatest to date.
