Aston Villa manager Unai Emery believes his side are capable of stirring a dramatic Champions League fightback when Paris Saint-Germain travel to Birmingham for the second leg of their quarter-final on Tuesday defending a 3-1 lead.

Despite seizing the advantage at the Parc des Princes last week, Emery’s men were outclassed by Luis Enrique’s  French champions. The size of the task facing Villa is considerable.
