Real Sociedad striker Carlos Vela is a target for MLS.
Eduardo Hernández, Vela's representative met up with Colorado Rapids club delegates at the weekend in Columbus, (Ohio) and later with MLS officials this week.
"It could be now or in two years or maybe three, we don't really know.
"There is much to consider, but we are of the thought that no doors should be closed. We don't want to limit Carlos' options, and that is why we are listening," said Hernandez.
