The Parc des Princes chief has rubbished details of the Argentine's contract that have been published in the French media
Paris Saint-Germain sporting director Leonardo has branded a report saying Lionel Messi is on a €30 million (£26m/$35m) per year contract "completely false" and "unacceptable".
PSG pulled off arguably the biggest coup of the summer transfer window by signing Messi, who became available as a free agent after Barcelona announced they were unable to tie him down to a new contract due to their struggles to get below La Liga's wage limit.
The 34-year-old signed a two-year deal with the Ligue 1 giants, but L'Equipe reported he has been promised a third season worth €40m (£34m/$47m) and a yearly bonus of €15m (£13m/$18m).
