Atletico Madrid increased their lead at the top of LaLiga Santander to seven points with a victory at Ipurua and they still have a match in the hands of the runner-up Real Madrid.
The locals went ahead after 12 minutes in unusual circumstances with the goalkeeper Marko Dmitrovic beating opposite number Jan Oblak from the place. The Serb confidently stroked the ball down and to the left, while Oblak dived to the other side.
Atlético managed to overcome their surprise and equalize the game five minutes before the break. Luis Suarez demonstrated a quick rush to take the lead, but the keeper made a spectacular diving save.
Diego Simeone made two changes halfway through, introducing Joao Felix and Lucas Torreira instead of Thomas Lemar and Angel Correa.
Atleti continued to push the winner during the second half, but their dominance of the ball provoked few chances.
Its urgency intensified in the final stages and Dmitrovic made an excellent stop to deny Joao Felix in the 86th minute, shortly after Yannick Carrasco has thrown a free kick over the crossbar.
Two minutes later, the visitors received a penalty after judging a VAR call Anaitz Arbilla having committed a foul on Suárez.
The Uruguayan himself stepped up and, seemingly oblivious to the pressure, ate a fresh Panenka over Dmitrovic.
Eibar shouted for a penalty at halftime Stefan Savic appeared to control the ball with his arm in the box, but nothing was given and Atlético left Guipúzcoa with all three points.
