Hartlepool United are upset seeing Luca Murphy sign with Fulham.
Sky Sports says National League club Hartlepool say they will 'will be vigorously pursuing' compensation from Fulham for Luca Murphy.
Murphy was released by Hartlepool after a January move to Fulham fell through.
The 17-year-old joined Fulham on a professional deal on Friday.
Murphy initially came through the youth system at Newcastle United.
