Chelsea signed Radamel Falcao on loan for free, according to alleged leaked contract

A leaked document has shown Chelsea did not have to pay a fee to bring Radamel Falcao to the club on loan from Monaco.

The Colombia international has scored one goal in 11 games for the Blues, but has been out of action since October with a thigh injury.

An image of the alleged contract, published on the Football Leaks website, says Falcao was loaned to Chelsea free of charge, with the clubs having agreed a £38m purchase option at the end of the season.

Falcao spent last season on loan with Manchester United, with reports hinting that Louis van Gaal's side paid a substantial fee for his services - he scored four goals in 26 Premier League appearances.

The documents also show that Chelsea have until April 29, 2016 to notify Monaco in writing of their wish to sign Falcao.

"It is explicitly agreed that no fee is charged to Chelsea by AS Monaco for the temporary transfer of the player's registration," the document states.

Chelsea declined to comment on the document.

Falcao was rumoured to be returning to Monaco earlier this month but the Ligue 1 club ruled out that possibility because of his injury status.
