Real Socieadad goal scorer Xabier Prieto (R) in action against Las Palmas

Real Sociedad maintained their push for a top-four spot in La Liga __with a 1-0 win at Las Palmas on Friday.

The visitors took advantage of a horrendous goalkeeping mistake to move a point behind fourth-placed Atletico Madrid, who host Barcelona on Sunday, live on Sky Sports.

The game in Gran Canaria looked to be heading for a goalless stalemate until, 16 minutes from time, Las Palmas goalkeeper Javi Varas inexplicably passed the ball straight to Sociedad midfielder Xabi Prieto on the edge of the box.

Prieto took one touch and, __with Varas out of position to the right of his goal, he had the simplest of tasks to slot into an unguarded net.

That consigned unlucky Las Palmas to a fourth successive La Liga defeat and saw Sociedad move to within a point of fourth-placed Atletico, who play Barcelona on Sunday.
