Cardiff City have completed the signing of Polish youngster Erwin Sak.
The 18-year-old goalkeeper has penned a permanent deal at Ninian Park after spending the previous week on trial.
Cardiff were able to complete a deal because Sak had been released by his previous club Sokol Pniewi.
Meanwhile, David Forde has been denied a move to Dundee United.
The Irish defender could have been in line to feature in the Scottish League Cup final as United want him on loan.
But he could not move because of the Fifa rule which deems a player cannot play for three clubs in separate countries in one year.
He had featured on loan at Luton, but also played for Cardiff in the Welsh Cup at Welshpool - which made him ineligible for a move to Scotland.
"To my mind it's an absolutely ridiculous rule," said Cardiff manager Dave Jones.
