The match exposed the huge challenge of competing at Europe’s highest level.
Slovak champions Slovan Bratislava suffered defeat in their opening match of the Champions League league phase, losing 6-1 away to defending champions Paris Saint-Germain.
Although Slovan fielded their strongest available line-up, it was no match for their opponent.
Ferran Torres scored a hat-trick in Wednesday’s match at the Parc des Princes, while Ousmane Dembele added two goals for the favourites and Fabian Ruiz scored once.
Suleiman Camara scored Slovan’s consolation goal when the outcome was already decided at 5-0.
