A very similar situation to that of Fabio Carvalho this season appears to be arising, with the main difference, of course, being that O’Neill is yet to make his senior debut for the Cottagers.
Harvey Elliott and Patrick Roberts were also prized away from Craven Cottage in their youth, and the West Londoners will be desperate to halt a repeat of those events with O’Neill.
There are four other youngsters who could leave this summer, with the club currently pursuing fresh agreements with Sonny Hilton, Steven Sessegnon, Adrion Pajaziti and Tyrese Francois.
O’Neill has chipped in with six goals and three assists from mainly a left midfield role in Premier League 2 this season, and with the division’s audience and credibility growing in recent years, it is no surprise to see the 19-year-old gain admirers in higher places.
First team football for anyone in the Premier League next season looks very unlikely for O’Neill, but given the talent that Fulham have produced in the last few years, clubs will be circling around their next generation, especially when their contract situations are decreasing transfer fees.
Quiz: Which club did Fulham sign these 24 players from in the 2000s?
The lure of Premier League football and the momentum, on and off the pitch, that Fulham appear to be taking into the top-flight next season, may be enough to convince the above quartet and O’Neill to commit their future to the club this summer.
However, Marco Silva will need to show greater intent to promote from within next season, to convince the up and coming talents at the club that their future lies at Craven Cottage.
Handing so many opportunities to Carvalho took something of a leap of faith at the beginning of the season from Silva and it will be interesting to see if any candidates to emulate his impact emerge in pre-season.
