Last summer Manchester United secured forward Anthony Martial for a reported fee of £61.5 Million.
According to an alleged leaked document it claims that the fee of £61.5 Million would be a final cost for the player if all the clauses in the deal are met.
So far United have refused to comment on the document, which has appeared on the Football Leaks website.
The document is said to show all the details in relation to the French stars move from Monaco during last summer’s transfer window.
The document claims that the initial fee of £38.5 Million for the player is to be paid in two installments – £15.4 Million within three days of his transfer, and £23.1 Million on July 1.
This would be followed by three further potential payments of £7.7 Million if 25 goals are scored in the first team. £7.7 Million if Martial makes 25 appearances for the club and a further £7.7 Million if the youngster makes 25 appearances for the French national team.
