In most cases, transfer costs are paid in installments. Any team considering a large expenditure on a superstar player must examine the whole commitment. In truth, the stated total headline transfer cost frequently differs from the sums paid to the selling club. For example, if a player's contract expires at the end of this season and he decides not to sign another deal, he can be claimed for free. However, if the player wants to move to another country, then a transfer fee will have to be paid. There are two ways to pay for a transfer: by way of a one-off payment or through monthly payments. Some players with high salaries require a long time to be resolved, so their clubs may prefer them to be paid in several instalments instead of all at once. The one-off payment is made at the time of the transaction, either at the start of the transfer window or when the player signs his contract with the new club. This is usually the majority of the cost of the transfer. The monthly payment is made during each month that the player plays for his new club.
