LONDON: Manchester United’s post-Mourinho bubble burst with a loud pop as Ole Gunnar Solskjaer’s eager pupils were taught a decisive lesson in how to play European two-leg football by Paris Saint-Germain.

The French outfit won 2-0 at Old Trafford in the first leg of their second round Champions League tie with goals from Presnel Kimpembe and Kylian Mbappe and despite the injury absences of their superstar strikers Neymar and Edinson Cavani.

In the night’s other tie Roma defeated Porto 2-1 with two goals from Nicolo Zaniolo against a consolation response from Adrian Lopez.

At Old Trafford a measure of PSG’s command was that United never threatened veteran keeper Gigi Buffon even before they were reduced to 10 men in the closing minutes after Paul Pogba was sent off for a second yellow card.

The first competitive encounter between the clubs thus saw the Norwegian’s first European game in charge end his 11-match unbeaten start in charge. On top of that United lost both Jesse Lingard and Anthony Martial to injuries at the end of  the first half.

PSG boasted a player with a point to prove against United in Angel Di Maria who rose to the occasion amid the jeers to superbly provide assists for both goals.

He recovered from a painful tumble into the pitch fencing in the first half to provide the second-half corner which Kimpembe volleyed home in the 53rd minute.

Di Maria’s pass was then swept home by Mbappe six minutes later to leave United flailing, with David De Gea producing some fine stops to prevent their difficult task in France becoming even more difficult.
