Chelsea striker Islam Feruz has returned to Stamford Bridge after Championship outfit Cardiff City opted not to sign the Scotland Under-21 player on loan.
The 19-year-old spent last week on trial with Russell Slade's squad with a view to signing until the end of this season.
However, Slade confirmed that the deal would not be taking place, telling Wales Online: "We've made a decision on Islam and he's gone back to Chelsea."
Feruz has four and a half years to run on his Blues contract and has just returned from a spell with Greek League club OFI Crete.
