Oscar de Marcos denied Real Sociedad coach David Moyes a first derby win with an equaliser for Athletic Bilbao.

Carlos Vela's early headed goal got hosts Real Sociedad got off to a dream start and Moyes' side missed several chances to extend their lead before half-time.

They were made to rue those misses when De Marcos equalised in the 62nd minute, meaning the game ended 1-1.

Athletic had to play the final 10 minutes with 10 men when Aymeric Laporte was sent off, but Real Sociedad were unable to make the extra man count, and remain 14th in the table.

They are five points behind Athletic, who occupy 10th place.
