(Reuters) -Second half goals from Kylian Mbappe and Bradley Barcola secured Paris St Germain a hard-fought 2-0 win over visitors Real Sociedad in the first leg of their last-16 Champions League tie on Wednesday.

The Basque club, who arrived at the Parc des Princes unbeaten in this year's competition after topping Group D, were arguably the better side until Mbappe fired home a volley after he pounced onto Marquinhos' corner to give PSG the lead in the 58th minute.
