#3 Manchester City 1-2 Lyon
Manchester City have famously struggled to live up to expectations when it comes to Europe, and if this week's opening result is anything to go by, this year will be no different.
The result was easily the biggest shock of the opening round, with many fans predicting a comfortable victory for Manchester City, who have started the Premier League season strong.
It's unclear exactly what caused such a dismal display from City, who looked a shadow of their record-breaking Premier League side from last season.
Manager, Pep Guardiola spent the game in the stands, seeing out a touchline ban from last season's competition, and perhaps this was one of the reasons the team looked so uninspired.
