A report in Express and Star outlines how the Catalan giants are yet to pay the training compensation of £235k which the Baggies are due.
The Black Country club have made several attempts to contact Barcelona directly to pay the fee but no payment has been forthcoming, with Barry subsequently joining Aston Villa in January in an €800k deal.
It is said that West Brom will now submit their report to FIFA with the support of the EFL, while in a separate development they are also seeking the advice of lawyers to evaluate if the Catalan club could legally sell the player as they had never paid his relevant transfer fee.
Born in Birmingham, Barry has dual English and Northern Irish nationality but previously represented Republic of Ireland’s youth teams before switching to England at Under-16 level.
