Las Palmas scored a stoppage-time winner to beat Eibar 3-2 in the first leg of their last-16 clash in the Copa del Rey on Thursday evening.
Eibar twice led on home soil, but the match turned in the final 10 minutes when Jose Luis Mendilibar's side were reduced to nine men in the space of five minutes, allowing Momo to come up with a 91st-minute winner for the visitors.
The home side opened the scoring in the 10th minute through Izet Hajrovic, but Las Palmas were back on terms just six minutes later when Aythami Artiles converted from close range.
Eibar were again ahead in the 20th minute through Saul Berjon, but Juan Carlos Valeron produced his second assist of the match to set up Mubarak Wakaso for 2-2 on the hour mark.
Chances were few and far between for long spells of the second period, but Eibar were reduced to 10 men in the 82nd minute when Hajrovic saw red for a lunge on Vicente Gomez, before Gonzalo Escalante was also sent off for a poor challenge on Wakaso.
It did appear that Eibar would hold on to take a 2-2 draw into the second leg next week, but Las Palmas had other ideas as Momo converted in second-half stoppage time to cap what was an event-filled match in the Spanish Cup.
