The future of Sunderland winger Alvarez has still not been decided.
However, the Wearside club did not want to sign him on a full-time contract, and planned to send him back to Inter at the end of last season. Their resistance is due to Inter’s failure to make a decision on a planned knee surgery the winger needed, according to the report.
FIFA have now got involved in the deal, in an attempt to sort out his contract and divide which club Alvarez should be registered to.
There was a potential way out for both clubs, with San Lorenzo in Alvarez’s homeland of Argentina reportedly agreeing a deal to sign the winger on loan.
This would have meant he could keep playing football whilst the case was sorted throughout the campaign, but FIFA have once again intervened and dealt a blow in their attempts to get Alvarez off their books.
The international federation have ruled that Alvarez cannot move to any club until the case around his ownership is clarified, meaning that Sunderland begrudgingly keep ahold of the 27-year-old whilst Inter refuse to claim ownership over him.
