Paris: Paris Saint-Germain are unaffected by the World Cup corruption investigation launched against chairman Nasser Al Khelaifi, a source close to the club has said.

Swiss prosecutors revealed this week they are probing Al Khelaifi and disgraced former Fifa executive Jerome Valcke over the sale of media rights for World Cups from 2018-2030. A villa on Sardinia that Italian police say Al Khelaifi used as “a means of corruption” has been seized and searched. An aide close to Khelaifi said he denies all the accusations and has done nothing wrong.

The probe has cast a shadow over an exciting start to the season at the Parc des Princes following the signing of Brazilian superstar Neymar in a world record 222 million euro ($262.5 million) deal and the arrival of French teenage sensation Kylian Mbappe.
