The Champions League returns this week and some of the world's biggest clubs are attempting to dethrone reigning champions Paris Saint-Germain by lifting the European Cup in Budapest, Hungary, next May. Six Premier League teams, Spain's heavyweights of Barcelona, Real Madrid and Atletico Madrid and Bayern Munich will all back themselves to topple PSG, while Italian champions Napoli could be a dangerous outsider.
Matchday one -- spread over three days -- has thrown up some box office clashes including Bayern Munich against Chelsea, Newcastle at home to Barcelona and City against Napoli.
