Born in Piatra-Olt, Raț began his football career when he joined the local team Rapid Piatra-Olt aged seven in a team trained by his father. In the summer of 1994, Raț went on a trial with Universitatea Craiova. He impressed coach Anghel Mităchescu and joined the club's youth system at age 13. When Mităchescu found out that he was going to be released from his duties by club president Rodion Cămătaru, he transferred the entire junior squad at the Divizia B side Constructorul Craiova. Raț's career for Constructorul, however, ended shortly after due to the club's financial problems, in 1995. In the winter of that year, Raț was noticed by Tudorel Stoica, who attended a futsall tournament held in Balș. Stoica wanted Raț to join Steaua București's youth system. Despite both Stoica and youth coach Bujor Hălmăgean being impressed by the young player, Raț never joined Steaua because according to his father, the club refused to pay the youth, Raț being forced to support himself in Bucharest. Taking advice from his former coach Mităchescu, Raț joined Sporting Pitești, the team trained by former international player Nicolae Dobrin. In his first match, Raț was substituted for the last 10–15 minutes of the game after he had scored five or six goals.
