The top-flight new boys have been handed a  three-point penalty, with one suspended, by governing body LFP for overzealous celebrations from their fans in the aftermath of their final home match of last season, in which they secured both the Ligue 2 title and promotion.

Supporters lit flares and staged a pitch invasion after the final whistle, with the match referee attacked as the ugly scenes marred the end of their two-year stay in the second tier.

The principality outfit have also been ordered to play one home game behind closed doors.

"Regarding the seriousness of the facts, Monaco are condemned to one match behind closed doors and a three-point penalty, including one suspended, for the next Ligue 1 season," an LFP statement read.

The club have aired their disappointment at the severity of the punishment with a statement on their official website reading: "AS Monaco FC wishes to express its surprise following the decision by the Disciplinary Committee of the LFP to impose a penalty of one game to be played behind closed doors, and three penalty points, of which one is suspended.

"The club believes this is a harsh punishment given the significant efforts the club has made over recent years to improve the management of home games and to ensure that due respect is given to all principal participants, including players and officials.

"Furthermore, AS Monaco FC has always condemned in the strongest terms, any violent conduct against the referees.

"Stade Louis II has always been synonymous with an atmosphere of friendliness and respect for both opponents and referees.

"The club will await the official notification before considering an appeal."

The news will come as a blow to Claudio Ranieri's big spenders, who are aiming to challenge champions Paris Saint-Germain for the title next term and have already brought the likes of Radamel Falcao, James Rodriguez and Joao Moutinho to the Stade Louis II.

They further strengthened their defensive ranks with the signing of 21-year-old centre-back Nicolas Isimat-Mirin for an undisclosed fee from Valenciennes on Friday.
