Leeds United famously defeated Champions-in-waiting Manchester City 2-1 at the Etihad last season. Stuart Dallas scored the winner in stoppage time, despite Leeds playing the second half with ten men and having to defend for their lives. Dallas' two goals in the match where the Whites' only shots in the match, compared to 29 for the home team.
However, as incredible as the achievement was, it's important to remember the context. The match came between City's two legged Champions League quarter-final against Borussia Dortmund and saw the City team heavily rotated. In fact, Pep Guardiola only started four players against Leeds that had played in the first leg against Dortmund. Phil Foden and Ilkay Gundogan were brought on from the bench in the second half but Kevin De Bruyne remained an unused substitute.
Of course, this shouldn't taint the achievement of the Leeds team that day but it was certainly helpful that they didn't face the full force of Guardiola's side. Thanks to City progressing to the Champions League semi-finals this season, they could be set for a similar boost when they face the Champions in May.
