Early career

Sepsi did not feature in any Ligue 1 matches in the 2005–06 season, only being fielded in a couple of games for the Coupe de France.^[2] Following the departure of Bölöni in the summer of 2006, he returned to Romania, joining ACF Gloria 1922 Bistrița where he impressed overall, helping them to a final sixth position in the top division and qualification to the UEFA Intertoto Cup; he was also team captain.

Benfica

On 12 January 2008, Sepsi signed a five-and-a-half-year contract with S.L.

In August, he was loaned to La Liga club Racing de Santander in a season-long move.^[3] He made his competitive debut with the latter on 31 August 2008, in a 1–1 home match against Sevilla FC,^[4][5] and contributed with 19 games – 14 starts – as the Cantabrians finished in 12th position, thus retaining their division status.
