It's less well-known than Real Madrid vs. Atletico Madrid, and even a little less well-known than Real Madrid vs. Getafe, but the match between Los Merengues and Rayo Vallecano is a local Madrid derby, and it's a big one this season. Real Madrid will be expected to win as they are in every game, save for the matches against Barcelona (and possibly at the Mestalla), but Rayo are no pushovers.
Rayo Vallecano were expected to be involved in a relegation battle this season, but are instead firmly in the top half and competing for European places. They defeated fellow European rivals Levante 5-3 last week in a spectacular performance and they won't be expecting a loss before the match starts. They are also rested, while Madrid are returning from a trip to Moscow in the UEFA Champions League.
Karim Benzema will be out for Madrid, and will likely be replaced by Gonzalo Higuain in the starting XI. Angel di Maria did not travel to Moscow after making a substitute appearance last week for Madrid, and could potentially return to the starting XI against Rayo.
Game Date/Time: Sunday, Feb. 26, 10:00 a.m. ET, 4:00 p.m. local
Venue: Estadio del Rayo Vallecano, Madrid, Spain
TV: ESPN Deportes (USA), GolTV (Canada)
