Juventus coach Antonio Conte had an 10-month suspension in Italy for match-fixing violations extended worldwide by FIFA on Friday, barring him from coaching at his team's Champions League game at Chelsea next week.

Conte's ban "covers all types of matches, including domestic, international, friendly and official fixtures,'' FIFA said in a statement.

Juventus, a two-time European champion, begins the Champions League group stage away to titleholder Chelsea on Wednesday. The group also includes Shakhtar Donetsk and Nordsjaelland.

FIFA said the sanction could be changed if Conte wins an appeal, "such as the one currently pending at the National Arbitration Tribunal for Sport in Italy.''

That case will be heard next Friday.

Conte was suspended by the Italian football federation in the offseason for failing to report match-fixing by an opponent when he coached then-Serie B team Siena in the 2010-11 season.

Conte later guided unbeaten Juventus to the Serie A title this year in his first season as coach.

Juventus technical director Massimo Carrera has taken charge at matches this season while Conte and his assistant Angelo Alessio are banished from match-day duties.

Conte has been criticised by at least one rival coach for continuing to take training sessions.

FIFA said it was preparing to extend suspensions worldwide to other players and officials implicated in the ongoing Italian match-fixing investigation.

"FIFA is currently reviewing additional documentation provided by the (Italian federation) in relation to other sanctions,'' football's world governing body said.
