Dalby spurned the Rapids in attempt to make it in Europe. He spent much of 2007 in search of a club trialing at Celtic in Scotland, Nuremberg in Germany and Siena in Italy. A deal to play for Preston North End in England fell through because of work permit problems, and he ended up on the "espoirs" team at Charleroi, never playing in the Belgian First Division.
Dalby, a Notre Dame midfielder, was originally selected by Colorado with the 17th overall pick in the 2007 MLS SuperDraft.
"We took a risk when we drafted Greg, knowing he had the ability and desire to play in Europe," said Rapids head coach Fernando Clavijo. "That risk paid off today as we have signed a top, up-and-coming midfield talent."
