Champions League: Matchday one – in pictures

After last season's lacklustre campaign Michael Carrick's seventh minute goal settled a few nerves inside Old Trafford. Though not for long, as Nani's second half penalty miss and the fact that Galatasaray hit the woodwork on a couple of occasions meant it was squeaky bum time for the United faithful for most of the match.

Celtic Park saw the return of Champions League action for the first time in four years. Neil Lennon's side started and finished strongly but survived some scares of their own to ensure a fourth straight European Cup clean sheet at home to these particular Portuguese visitors.

Barcelona's Lionel Messi causes consternation in the Spartak Moscow defence. The Russians, who were 2-1 ahead, had good reason to fear La Pulga Atómica as his two goals meant that instead of inflicting Barça's first home defeat in 17 European games, Spartak lost the match.

Bastian Schweinsteiger cast aside the bitter memories of Bayern's Champions League final defeat in May by putting the German side ahead as they kicked off the new campaign against Valencia. Their lead was doubled in the 76th minute by a 20 yard drive from Toni Kroos, above sixth left, before Nelson Valdez snatched a consolation goal during injury time.

Romania's CFR Cluj finally managed a Champions League away win at the sixth time of asking at the expense of Portugal's Sporting Braga. Their victory was against the run of play but Cluj's quick counter attacks and ruthless finishing gave them the upper hand. Cluj's goals were scored by former Braga player Rafael Bastos, seen here, above left, challenging Custodio. Final score: Sporting Braga 0-2 CFR Cluj Photograph: Hugo Delgado/EPA

Lille's Mathieu Debuchy is beaten to the ball by Bate Borisov's Maksim Borachev, which summed up the match as Bate Borisov overpowered the French side with a slick first-half display of attacking football. Final score: Lille 1-3 Bate Borisov Photograph: Denis Charlet/AFP/Getty Images
