French midfielder Jean Yves De Blasiis signed for the Canaries on a Bosman free transfer from French club Red Star Paris. Jean had impressed in pre-season matches at Southend and in Scandinavia and so was offered a contract by Bruce Rioch. A cruciate knee injury sustained in training on 17th March 2000 ruled him out of competitive action until the latter part of 2000 (somewhere between September and Christmas). Despite returning and playing for the Reserves and First Team (7 appearances in 2000/01), Norwich announced on 3rd April 2001 that Jean would be released at the end of the season when his contract expires. The club felt that his injury had made a permanent impact and would hinder his ability to play at the required level for Division One

Jean later joined French side FC Istres Ville Nouvelle

He is currently of the club staff at FC Girondins de Bordeaux, the club where he started his career. He also played for Stade Malherbe and then Red Star Paris before joining the Canaries.
