FIFA is investigating how celebrity chef Salt Bae gained "undue access" to Argentina's on-pitch celebrations after the World Cup final.

Salt Bae, the Turkish chef and social media presence whose real name is Nusret Gokce, posted several photos of himself with the World Cup trophy on social media after Sunday's game.

The chef, who owns a chain of luxury steakhouses and rose to fame through a series of viral internet videos in 2017, was also seen attempting to pose for a photo with Lionel Messi and several Argentina team-mates.

His presence in the immediate aftermath of the trophy presentation is now the subject of a FIFA investigation after attracting widespread criticism.

A widely reported statement from world football's governing body read: "Following a review, FIFA has been establishing how individuals gained undue access to the pitch after the closing ceremony at Lusail stadium on December 18.

"The appropriate internal action will be taken."

Earlier this month, Salt Bae posted an image on Instagram of himself at a World Cup match alongside FIFA president Gianni Infantino and Brazil greats Ronaldo, Cafu and Roberto Carlos.
