Barcelona's contract problems extend beyond Lionel Messi and Neymar with Sergio Busquets the latest first-team star demanding a pay rise.
The Spanish midfielder does not grab headlines like his attacking team-mates but, with an unprecedented ability to dictate the game from midfield, is arguably just as important to Luis Enrique's team.
As a result, Busquets is demanding a significant increase in his weekly wage, which Barcelona promised to him without a second thought. However, self-imposed financial restrictions, brought about by their already ginormous wage bill, has prevented them from offering him what he wants.

Busquets is very keen to stay so there was not much for Barcelona to worry about, but, according to Spanish newspaper Marca, Paris Saint-Germain are ready to give them a big problem.
Any of Europe's biggest clubs would jump at the chance to sign Busquets, but no club has shown a firmer interest than PSG. They are willing to pay as much as €100m to Barcelona while also offering the player a contract worth €16m-a-year.
Having crashed out of the Champions League, PSG's season is effectively over and they are already planning for the next campaign. While the Ligue 1 title should once again come easily, the Qatari owners are desperate to win Europe's elite competition and will be looking to strengthen the squad to maximise their chances.
As a result, PSG are looking for an answer from Busquets in the very near future and the midfielder has responded by sending his agent, Jose Maria Orobitg, to hold talks with Parc des Princes officials.
Barcelona's tremendous success has been to the envy of world football, but the challenge of keeping a star-studded squad together has left the Nou Camp club at a breaking point. The contracts of Neymar and Messi will be renewed this summer with the Brazilian almost doubling his wages to €22m-a-year.
Their wage bill already stands at €419m-a-season which is perilously close to the €421m limit set by La Liga's financial fair play rules and represents 73 percent of the club's annual budget.
Sticking the boot in, they have also failed to find a new shirt sponsor for next season. Talks have stalled with Qatar Airways and failure to find a new sponsor before June 30 would leave a gaping hole in their balance sheet.
President Josep Maria Bartomeu and his board will have to step down if they do not bring the situation under control, leaving Busquets's pay rise in serious doubt.
