Atleti fined for signing player involving third party

FIFA does not allow third-party investors to be involved in agreements with clubs and players. 

The organisation released the news on Friday, announcing that Atletico had violated article 18 of the 'Regulation on the status and transfer of players'.

'Los Rojiblancos' have previously undergone a transfer embargo for breaching rules in signing minors - the club were banned from two transfer windows and fined £439,873. 

This news comes after Atletico's UEFA Super Cup 4-2 victory against city rivals Real Madrid on Wednesday night.
