In an April 8 update, the Spanish Football Association revealed details of the referee assignments for the 30th round of La Liga, when Mateusz Lahoz will referee a much-anticipated marquee match - this week's upcoming Spanish national derby.
Real Madrid will then face Barcelona on their home turf at 3 a.m. BST on Sunday.
It is worth mentioning that Lahoz has previously enforced five national derbies, in which Real Madrid won 3 and lost 1, and Barcelona won 1 and drew 1. The two sides are of equal strength, and the results of the matches are often full of suspense.
