Columbus Crew head coach Robert Warzycha has confirmed that two Costa Rican players are training with the team.
The Crew are in training up until the MLS Cup final on Sunday and Warzycha said it is a great time of the year to take a closer look at some potential new faces for next season.
"This is obviously the time of season where you can bring somebody in to take a look at," Warzycha told the Columbus Dispatch.
"That's a good thing. We bring the guys here because we can see if they're better than the guys we have now."
