Fulham have completed the signing of winger Ryan Williams from Championship side Portsmouth for an undisclosed fee.
Williams has impressed since breaking into the Pompey first-team this season and featured for Fulham's reserves against Wolves on Monday night ahead of a potential move.
The 18-year-old winger, who came through the youth ranks at Fratton Park, has signed a two-and-a-half year deal at Craven Cottage.
Portsmouth were reluctant to part with the Australian but the Championship club's financial situation has forced their hand, although the transfer fee has not been disclosed.
