The Court of Arbitration for Sport decided on Friday to continue the suspension of Michel Platini by Fifa until 5 January. Another setback for the French who still remains under the threat of a more severe sanction. Verdict before Christmas.

Certainly, the situation is complicated for Michel Platini. The French, former favorite for president of FIFA, had his 90-day suspension upheld on appeal, Friday, December 11, by the Court of Arbitration for Sport in Lausanne (CAS).

TAS "has determined that maintaining the current temporary suspension was not likely to cause irreparable harm to Michel Platini for the moment," do we learn in a statement, Friday, December 11 in the morning.

The UEFA president "remains confident in the merits of the case and the strength of his case," he told AFP his lawyer Thibaud Ales, in the wake of the announcement of this decision.

Platini, as well as the former president Sepp Blatter instance, was suspended for 90 days on October 8, pending a judgment on the merits, as he is suspected of being directly involved in an unfair payment case. It accuses the president of UEFA in 2011 to have received a payment of 1.8 million Blatter for a mission between 1999 and 2002.

The Ethics Commission of Fifa, Blatter who will receive 17 December Platini and the next day, should take a final decision in place of the two men before Christmas Eve, said an inside source.

Fifa ordered to make a quick decision

If the CAS decision fell like a cleaver for Platini clan, it remains albeit with considerable restrictions on the location of FIFA. The Ethics Commission was ordered to order not to extend the temporary suspension of Platini 45 days, possibly as required by Article 85 of the Ethics Code of the proceedings.

CAS said "that such an extension would constitute an excessive and unjustified restriction of the right of Michel Platini to access to justice, would cause him irreparable harm and would tip the weighing of interests in its favor." Or, more simply, it would deal a definitive blow and arbitrary his presidential ambitions.

If the Ethics Commission wishes to the President of UEFA disqualified in the fight for the leadership of FIFA, it will have no other choice but to sanction a permanent basis.

The suspension of Michel Platini, which ends January 5, for now prevents the validation of the candidacy of the French to the presidency of FIFA. The vote will take place February 26, 2016
