Kevin Gameiro came off the bench to net a hat-trick in just five minutes as Atletico Madrid won 4-1 at Sporting Gijon.
Belgian winger Yannick Carrasco had put the visitors in front early in the second half, only for Sergio Alvarez to equalise within a couple of minutes.
Gameiro came on just after the hour to replace Fernando Torres and made a telling impact for Los Colchoneros.
The Frenchman rounded the goalkeeper to put Atletico ahead again with 10 minutes left.
Before Sporting could regroup, Gameiro had struck again after the Gijon defence failed to clear their lines and then swiftly completed his treble with a low shot into the bottom corner following a breakaway.
