Pep Guardiola's side dominated the opening period but it was Osman Bukari who scored the first goal on our return to the Champions League.
However, our team conceded shortly after the restart and ended up losing 3-1 against the team which won the competition by beating Inter Milan in last season's final.
Omri Glazer was superb as he made 13 stops throughout the game, but it wasn't enough to claim a point.
Our next UCL test is the home game with BSC Young Boys on 4 October.
