Paris Saint-Germain and Valencia have played out a goalless draw in the first half of their Champions League last-16 encounter at the Parc des Princes.
The French side still lead 2-1 on aggregate following their win in Spain three weeks ago.
After a quiet opening, the visitors had the first decent opportunity when Roberto Soldado hit his shot at Salvatore Sirigu following an exchange of passes with Jonas.
Jonas then had a crack at goal himself, only for his long-range effort to fly well wide.
PSG struggled to create many decent chances as they tried to make life difficult for the visitors, but Javier Pastore had his shot blocked before hitting another straight at the goalkeeper.
