Real Madrid is attempting to arrange an exhibition game in the San Francisco Bay Area for late July.
Real is one of eight European soccer clubs featured in the Guinness International Champions Cup.
The venue choices appear to be Candlestick Park or Stanford Stadium.
The San Jose Earthquakes of the MLS are scheduled to open Levi's Stadium on Aug. 2 against the Sounders, perhaps eliminating the San Francisco 49ers' new stadium.
