The Portuguese goalkeeper was to sign last year on a free transfer from Charlton, but called off the deal before starting pre-season training due to a family bereavement.
As previously reported on this site, Peter Taylor has remained interested in the 25-year-old, and has now finally got his man.
The ex-Portuguese Under-21 international joins on a free transfer when his international clearance comes through on 5th July, signing a one-year contract.
