This is a list of Mexican football transfers in the Mexican Primera Division during the winter 2010 transfer window, grouped by club. Football has been played professionally in Mexico since the early 1900s. Since 1996, the country has played two split seasons instead of a traditional long season. There are two separate playoff and league divisions. After many years of calling the regular seasons as "Verano" (Summer) and "Invierno" (Winter); the Primera División de México (Mexican First League Division) have changed the names of the competition, and has opted for "Apertura" (opening) and "Clausura" (closing) events. The Apertura division begins in the middle of Mexico's summer and ends before the official start of winter. The Clausura division begins during the New Year, and concludes in the spring season.
