Crystal Palace have completed the permanent signing of midfielder Alex Marrow for an undisclosed fee from Blackburn.
The 19-year-old, who had been on loan at Selhurst Park since August, has put pen to paper on a two-and-a-half-year deal.
"I've been very impressed with Alex," said caretaker boss Dougie Freedman.
"It is good to see him join the club permanently and I'm sure he will become an important part of our squad for some time to come."
