Deportivo and Getafe strolled home in the Copa del Rey on Wednesday while Real Zaragoza won at Barcelona.
Barcelona have it all to do in the second leg of their quarter-final clash with Zaragoza after crashing 1-0 at Camp Nou.
The games appeared to be heading for a goalless draw before Carlos Diogo (pictured) popped up late on to snatch a crucial first leg advantage.
Deportivo have one foot in the semi-final door after coming from behind to secure a 4-1 win over Segunda Liga outfit Valladolid.
Vladimir Mantchev's 21st minute strike gave the visitors the lead, but Depor dominated after half-time at the Riazor.
Pablo Alvarez levelled matters and Rivera fired the home side ahead for the first time on the night after 67 minutes.
Depor added a third through Joan Verdu, but they soon found themselves a man light when Alberto Lopo was dismissed.
However, it failed to halt their charge with Juanma securing what could be the clinching goal deep into injury-time.
Getafe also secured a comfortable success after easing to a 3-0 win over Osasuna.
Maris Verpakovskis added the icing on the cake in the second half after efforts from Daniel Guiza and Alexis put the home side two-up.
