But RSL expects to move in a different direction, sources said, after coach Jason Kreis completed a scouting trip to Argentina earlier this week. Which player Kreis is pursuing, however, remains unknown.
Meanwhile, Adu's representative planned to meet with Celtic FC officials while they were in Denver to play the MLS all-stars.
Agent Richard Motzkin has put off interview requests from The Tribune over the past two weeks, but recently told the Scottish Sun newspaper that "my sole reason for going to the All-Star Game isn't to speak to Celtic, but some might say it would be a good time to talk if both parties are in the same place. Freddy has always said he wants to go to Europe at some stage in his career, and any player would have a lot of respect for a club like Celtic."
Media reports in Europe have said that Tottenham Hotspur of the English Premier League also is interested in Adu, after the 18-year-old enjoyed a spectacular run leading the U.S. Under-20 national team into the quarterfinals of the U-20 World Cup in Canada earlier this month.
Adu has not yet rejoined RSL, but could be back in training today. The heralded former trialist with Manchester United is RSL's highest-paid player at $550,000 a year, and could fetch a $2 million transfer fee. Adu also had been linked to Chelsea, but that club's interest has reportedly waned.
