UEFA Champions League scores, schedule: Manchester City vs. PSG highlights Matchday 2

The UEFA Champions League is back this week with Matchday 2, with games spread across Tuesday and Wednesday. Unlike Matchday 1, which saw games across three days, the conventional two-day window is back for the rest of the league phase and with some incredible matchups to look forward to. Tuesday's slate is highlighted by Manchester United's trip to Atletico Madrid, while Bayern Munich face a tricky test at Viking, and Wednesday's slate is a doozy.
