Barcelona’s financial woes are reportedly so serious they cannot register the likes of Lionel Messi or new arrivals Sergio Aguero and Memphis Depay ahead of the new season.
Eric Garcia and Emerson were also recently snapped up by the Catalan giants and similarly cannot be registered.
Barcelona president Joan Laporta has had to get creative in this summer’s transfer window, which is why the four players were all signed for free.
Will Lionel Messi be at Barcelona next season? Comment below
Laporta has been desperately trying to balance the books by offloading the highest earners or those out of favour at the club, but he isn’t currently having as much success as he would like.
Francisco Trincao has joined Wolves on loan for the season, and the Midlands club have the option to buy.
Junior Firpo is set to join Leeds in a deal worth around £13million, which will save Barcelona in the region of £8m per season.
Konrad De La Fuente and Jean Claire-Todibo have also both been sold, with the duo heading to Marseille and Nice respectively.
The two transfers save Barcelona around £9m in wages and deal payments.
Matheus Fernandes saw his contract terminated at the end of June, but he has plans to sue Barcelona for unfair dismissal.
These departures are not enough to keep Barcelona afloat, though, and Samuel Umtiti, Philippe Coutinho and Miralem Pjanic are all on the transfer list.
The La Liga giants are hoping that by selling the trio they can shed a further €200m (£171m) from the wage bill.
Perhaps the biggest worry in all this from a Barcelona perspective is the club may not be in a position to re-sign Messi.
Currently, the six-time Ballon d’Or winner is a free agent and the onus is on Barcelona to offer him a new bumper deal once they have cleared salary space to re-register him.
Messi is believed to be in contract talks with the club he has represented his entire professional career but other sides, including Paris Saint-Germain and Manchester City, may look to test the water with a contract proposal.
