The Chivas USA player could cost the Parkhead club £1 million if he impresses during his spell in Scotland. The 23-year-old, who played in America's 2-0 friendly win over Sweden in Los Angeles during the early hours of yesterday morning, is now expected to fly to Glasgow.
The highly-rated goalkeeper, who has also been linked with Arsenal, said: "It's always exciting when a great club such as Celtic are interested in you. Of course, I know all about the club - they are a world-renowned team with a fabulous history. "
