European champions Paris St-Germain failed to break down Athletic Club but remain well placed for Champions League progression.
Luis Enrique’s side are third, although only one point inside the top eight, while Athletic are 28th and in danger of elimination.
PSG dominated the game at San Mames and had most of the clear chances without beating home keeper Unai Simon.
Fabian Ruiz fired two good chances over the bar, with Simon making good saves to deny Senny Mayulu on either side of half-time.
The best chance came when Bradley Barcola raced through on goal and hammered a shot off the crossbar.
And Ruiz almost scored a late winner when he was denied well by Spain team-mate Simon – with Yuri Berchiche clearing off the line.
The Bilbao hosts, whose only shot on target came late on through Asier Hierro, sit two points off the knockout phase play-off places.
