Real Madrid are set to smash the world transfer record after agreeing a deal worth €180million to sign Kylian Mbappe from Monaco, according to a report in Spain.Madrid-based newspaper Marca claim that the Spanish and European champions have struck a deal that would easily eclipse the world-record sum of €105m that Manchester United paid to Juventus to sign Paul Pogba last year.Madrid will pay €160m up front and at least a further €20m in add-ons relating to Mbappe's success at the Santiago Bernabeu, it is reported.Here's how Twitter reacted:Mbappe's £160 million transfer fee works out at £10 million per goal he's scored hahaha!— Garry Carmody (@GarryCarmody) July 25, 2017I'd love Madrid to spend £160 million on Mbappe and he turn out to be a one season wonder— James Barber (@BigBarbs95) July 25, 2017Mbappe 160 million.
