PARIS, March 5 — Paris Saint-Germain’s preparations for Tuesday’s Champions League last-16 second leg away to Real Sociedad have been overshadowed by coach Luis Enrique’s handling of star man Kylian Mbappe.

PSG have suffered numerous humiliating defeats at this stage of the Champions League in recent years but they are ideally placed to advance to the quarter-finals this time after winning 2-0 at home to the Basque side in last month’s first leg.
