Michel Platini has expressed readiness to resign from European football governing body following the verdict that upheld his six-year ban on Monday.
Platini is the Union of European Football Associations [UEFA] president.
However, the Court of Arbitration for Sport (CAS) has reduced the ban on Platini to four years.
After the judgement, the former French international accepted to step down.
After CAS judgement, Platini said: “I am resigning from my duties as UEFA president to pursue my battle in front of the Swiss courts to prove my innocence in this case.”
He added that he considered the judgement “a profound injustice”.
However, the CAS panel was damning of Platini, saying his “behaviour was not ethical or loyal”.
Platini was found culpable by FIFA ethics committee over a 2m Swiss Franc (£1.3m) “disloyal payment”.
He was axed alongside his FIFA counterpart, Sepp Blatter.
Their original bans were, however, reduced from eight to six years by the Fifa appeals committee after they pleaded not guilty to the allegations.
Commenting on the CAS decision in the case involving Michel Platini, FIFA said in a statement:
“FIFA has acknowledged the decision rendered today by the Court of Arbitration for Sport (CAS) in the case involving Michel Platini.
“[It] has partially maintained the decision taken by the FIFA Appeal Committee on 24 February 2016.
“In particular, by lowering the sanction from six to four years and the CHF 80,000 fine to CHF 60,000.”
CAS said it found that Platini’s dealings with Blatter breached the ethics code of world governing body Fifa.
It ruled that his six-year ban was “too severe” and decided that a four-year punishment should be okay.
Four years is the equivalent to a presidential term in office.
It also said an 80,000 Swiss Franc (£57,200) fine should be lowered to 60,000 (£42,900), but stressed:
“The CAS panel was of the opinion that a severe sanction could be justified in view of the superior functions carried out by Mr Platini (Fifa vice-president and Uefa president), the absence of any repentance and the impact that this matter has had on Fifa’s reputation.”
UEFA has said it would meet on 18 May “to discuss next steps”.
“In the meantime, there will be no UEFA president appointed ad interim,” it added.
Platini had taken his case to CAS seeking to get the ban overturned, but a three-man panel said it “was not convinced by the legitimacy of the payment”.
The two said the payment in 2011 was made for consultancy work Platini had carried out for Blatter between 1998 and 2002.
They said that they had a “gentleman’s agreement” on when the balance was settled.
The matter is also being looked into by Swiss prosecutors.
Michel Platini played 72 times for France, scoring 41 goals, and was regarded as one of the best players in the world at the time.
