Sunderland have ensured they have recouped their outlay on Asamoah Gyan after the Ghanaian completed a permanent switch to the Middle East.Gyan’s drawn-out move to Al-Ain reached a conclusion yesterday after the striker agreed a four-year deal with the United Arab Emirates outfit, who initially took him from Wearside on a season-long loan deal last September.The Black Cats have not disclosed the fee in the deal, but it is thought to be around the £6m mark – which is in addition to the £6m Sunderland banked from allowing the 26-year-old to leave on loan.That is less than the club record £13m price tag Sunderland agreed to pay French outfit Rennes in the summer of 2010. But that sum was dependant on a number of add-ons, which were never triggered because of Gyan’s early exit.Sunderland have not made a loss on the deal, and will be relieved that they have finalised an agreement to remove Gyan, pictured from the wage bill.Likewise, Al-Ain are equally pleased to have landed their man after Gyan had been in demand from elsewhere in the Middle East, along with Turkish outfit Galatasaray.Gyan notched 25 times last season to help Al-Ain lift the league title and the oil-rich club are thought to have handed him a contract worth an estimated £140,000 a week – double the salary he was paid when he first arrived on loan.A statement from Al-Ain said: “Al-Ain Sports and Cultural Club can announce that Ghanaian striker, Asamoah Gyan has moved to Al-Ain.“Gyan moved to Al-Ain last year on a loan contract and he showed excellent harmony with the players on and off the pitch.“His high level of performance urged Al-Ain head coach Cosmin Olaroiu to ask the club’s management to secure the player on a permanent contract.”There was never any question of Gyan returning to Sunderland this summer after he left the Black Cats in the lurch by orchestrating a move away from the Stadium of Light following the end of last August’s transfer window.Boss Martin O’Neill made no attempt at a reconciliation with Gyan after succeeding Steve Bruce in December, and happily gave the go-ahead for Sunderland to cut their ties with the player.
