Javier Tebas is preparing a report for UEFA after concerns that the money spent by clubs in the English top flight is inflating transfer fees across Europe.
The LaLiga president fears that the Premier League's record spending of nearly £2billion pounds is a danger to 'sustainable European football', and as such has begun a written report to the governing body.
Whilst clubs in the English top flight racked up an enormous bill of almost £2b spent on players, Tebas' LaLiga clubs ranked behind Serie A and Ligue 1 for expenditure with just '£404million'.
