I'm not sure how this works outside of the transfer window, but Asamoah Gyan has left Sunderland. From Sunderland's official website:
Sunderland striker Asamoah Gyan is set to join United Arab Emirates side Al-Ain on loan.
Officials from Al-Ain made contact with Sunderland earlier in the week with a view to signing the player on a permanent deal. After further discussions overnight however, it was agreed that the striker would join the club on a season-long loan.
Sunderland AFC would like to thank the officials from Al-Ain for the professional manner in which they entered into negotiations and the club wishes all parties well.
Manager Steve Bruce said: "Anyone who has seen Asamoah play will know that he hasn't been himself in recent months. This option suits all parties at the present time and the club is well-protected in the deal.
"Asamoah has three years remaining on his contract and of course my wish would be that he finds his spark again and we see him in red and white stripes next season in the form that first attracted us to him."
Gyan never settled at Sunderland, although he certainly had some highlights. This leaves Nicklas Bendtner as their only "experienced" Premier League striker, with Connor Wickham and the Bishop, Ji Dong-Won the other forwards. After today's match against Chelsea, Sunderland host Stoke, travel to Norwich and host West Brom. Bendtner under 6 could be a useful option and his schedule compares favorably against Adebayor's, who is similarly priced.
