Copa del Rey 2016-17: Full Round-of-32 Fixtures and Dates Released

Defending champions Barcelona have been drawn against Segunda B side Hercules in the fourth round of the 2016-17 Copa del Rey, while Real Madrid will face Cultural Leonesa, also from Spain's third tier. 

Fourth-tier side Formentera—the lowest-ranked team left in the competition—will face last year's beaten finalists, Sevilla, in the two-legged round of 32. 

Here is the full draw:

Villarreal	vs.	Toledo
Formentera	vs.	Sevilla
Cultural Leonesa	vs.	Real Madrid
Hercules	vs.	Barcelona
Guijelo	vs.	Atletico Madrid
Racing Santander	vs.	Athletic Bilbao
UCAM Murcia	vs.	Celta Vigo
Cordoba	vs.	Malaga
Real Valladolid	vs.	Real Sociedad
Huesca	vs.	Las Palmas
Nastic	vs.	Alaves
Alcorcon	vs.	Espanyol
Sporting Gijon	vs.	Eibar
Granada	vs.	Osasuna
Leganes	vs.	Valencia
Real Betis	vs.	Deportivo La Coruna

The first legs of the fourth round will take place on Nov. 30, with the second legs set to be played out three weeks later on Dec. 21. 

All 20 La Liga teams enter the Copa at the last-32 stage, and Atletico Madrid have been paired up with Segunda B's Guijuelo.

Meanwhile, the Spanish top-flight's other European competitors, Celta Vigo, Athletic Bilbao and Villarreal, will face UCAM Murcia, Racing Santander and Toledo, respectively.

Valencia, semi-finalists in last season's Copa, have been drawn against recently promoted La Liga side Leganes, and Eibar and Sporting Gijon will fight out another all-top-flight clash.

The two teams currently sitting at the bottom of La Liga—Granada (20th) and Osasuna (19th)—have also been paired together.

Barca have won both of the last two Copas, and there will be many, especially in Madrid, hoping that they do not repeat the trick for a third time in a row this season.

Real have a particular incentive to go the distance in this season's tournament having been ejected from the 2015-16 edition for fielding an ineligible player in the fourth round. 

The likelihood of any of the big teams going out at the last-32 stage is highly unlikely, as the draw intentionally pits them against the lowest-ranked sides left in the competition.

However, the fourth round is always an entertaining spectacle as Spain's biggest sides host and visit some of the less auspicious clubs in the country.
