Born in Pristina, Ferati moved with his family to Pratteln, Switzerland, while he was still a child. He started his children's football with local club FC Pratteln and moved to the youth department of FC Concordia Basel in summer 2001. In summer 2005 Concordia loaned Ferati out to FC Basel to play in their U-21 team, with team coach Heinz Hermann, in the third tier of Swiss football. Ferati played 28 games with Basel's reserve squad during his loan period and afterwards he returned to Concordia, who at that time played in the Challenge League. The two clubs signed an agreement and Basel secured half the transfer rights of the defensive full back, with an option of a definitive take over. Ferati played for Concordia for one and a half years.
