Report: Platini didn't have written contract for £1.35-million FIFA payment

A lack of documentation is reportedly proving problematic for UEFA president Michel Platini.

Platini had no written contract for the CHF 2 million (£1.35 million) that FIFA paid him in February 2011, according to David Conn of the Guardian.

The payment is the subject of criminal proceedings against FIFA president Sepp Blatter, as the Office of the Attorney General of Switzerland (OAG) suspects it was "disloyal" and made "at the expense of FIFA."

Platini received a provisional 90-day ban from all football activities from FIFA's Ethics Committee last week.

Platini and Blatter told investigators they had an oral agreement about the payment when Platini worked as Blatter's advisor, Conn's report indicates. Platini has said the £1.35 million wasn't paid during that four-year period because of the football governing body's "financial situation at the time."

Conn writes:

Platini is understood to have told investigators he had agreed with Blatter, in 1998-2002, that he would be paid CHF 500,000 (£339,000) annually on top of his contractual CHF 300,000 (£203,465). The CHF 2 million appears to be explained as four years' worth of payments of that 500,000.

However, even if FIFA was unable to make the payment in 2002, Swiss law limits employee claims for money owed to five years - meaning the payment was barred and no longer legally owed in 2011. The OAG's criminal proceedings and FIFA's internal investigation are both thought to focus on this point, according to Conn.

Blatter and FIFA secretary general Jerome Valcke were also handed provisional 90-day bans last week. Both launched separate appeals.

Platini issued a statement Thursday insisting he's still determined to challenge for the FIFA presidency.
