There was a time when a reunion between Lionel Messi and Pep Guardiola looked distinctly possible, but on Tuesday they will be on opposite sides again when Paris Saint-Germain play Manchester City in the Champions League.
Had it not been for Jack Grealish, perhaps things would have turned out differently. City announced the £100 million ($139m) signing of Grealish from Aston Villa on August 5, the same day Barcelona revealed Messi would not be staying at the Camp Nou. A year ago, when Messi tried to force his departure from Catalonia, City appeared the most likely destination.
