Manchester City and Inter had to settle for a point to start their Champions League campaigns, after a competitive goalless draw in the north west of England. Elsewhere, a late winner for Paris was enough to see off Girona, while last year's runners-up Borussia Dortmund secured an impressive victory at Club Brugge. There were statement wins from Celtic and Sparta Praha, who marked themselves as teams to watch as the league phase progresses. We hear from Manchester City boss Pep Guardiola, Celtic captain Callum McGregor, Dortmund's double-goalscorer Jamie Gittens and Sparta Praha coach Lars Friis.
