Cork City striker Roy O'Donovan will have a medical at Fulham on Monday.
The 21-year-old is set to join the Premier League club for a fee that reports claim could rise to £530,000.
Fulham boss Lawrie Sanchez said the fee was "not a lot of money in Premiership terms but a lot of money in non-Premiership terms".
Sanchez added: "He has done very well at Cork and he will be going back there on loan until the end of their season. He's a young player for the future."
