Monaco have threatened to report any club that make an approach to Kylian Mbappe without their permission.

Mbappe, 18, has reportedly already been the subject of a €120 million offer from Real Madrid, with Arsenal, Man United, PSG and Barcelona all linked with moves.

A statement read: "AS MONACO notes with regret that "important" clubs of European football multiply contacts with Kylian Mbappé (and his entourage) without the permission of the club.

"AS MONACO intends to remind these clubs that such actions are contrary to Article 211 of the Professional Football League Regulations and to Article 18.3 of the FIFA Regulations and Status of Players Regulations.

"In order to put an end to this unacceptable situation, AS MONACO is considering asking the Professional Football League and FIFA to institute disciplinary proceedings against the offending clubs."
