The clever solution was made by the Spaniard, who added one day to the summer transfer window.
Thus the Spanish clubs have gained a competitive edge over other clubs from the top European leagues, as their "Transfer Deadline Day" will be on Friday 1st September, while teams from England, France, Germany and Italy will finish their traditional shopping on 31st August.
On 1 September the end of the window will also be in Albania, Armenia, Azerbaijan and Ukraine.
By the way, the Spanish federation also reported that the winter window will be held within the expected frame: from 1 to 31 January 2018.
As reminiscent - the dates of the transfer period concern the club that purchases the player. As a result on September 1st Spanish club will be able to buy a player from the English club, but English from the Spanish will not.
