Seattle Sounders have given trials to college pair Andy Rose and Jalil Anibaba.
English-born defender Rose played with UCLA Bruins and was the teams rookie of the year in 2008 after joining from Bristol City where he was captain of the youth academy teams.
21-year old midfielder Anibaba is from Santa Clara where he was named in three All-West region teams and comes with a high recommendation from head coach Cameron Rast.
“Jalil is a leader on the field for us. He comes to play everyday,” Rast told the Broncos official website. “His natural ability and talent allow him to make spectacular plays, both defensively and in attack.”
