With Real Madrid enjoying good momentum and Atletico Madrid on a bit of a slump, the city rivals meet in the semifinal of the Spanish Super Cup in Saudi Arabia on Wednesday in the first of three matches between the clubs in less than a month. After the Super Cup, Madrid and Atletico will clash again on Jan. 18 in the round of 16 of the Copa del Rey, and then on Feb. 4 at the Santiago Bernabéu Stadium in their second Spanish league match of the season.
