The Mirror reported this week that West Ham United had begun the process of tying down Domingos Quina to a new contract. The very highly-rated 17-year-old prospect cannot sign a long-term contract until he turns 18 next month and in the mean time it could be a very nervy period for West Ham.
Quina is one of the most sought-after young talents in English football and Paris Saint-Germain are among those interested. But could the biggest threat come a little bit closer to home for the Irons?
The East Londoners beat off competition from city rivals Tottenham Hotspur back in April 2016 (as reported by The Mirror at the time) to sign the Portugual Under-20 international but a change in landscape might suggest that he could consider Tottenham now if they went back in for him.
Bilic's image at the time of Quina's arrival was much stronger than it is now. The former Croatia boss had just led West Ham to a seventh-placed finish and it seemed for quite a while that a Champions League spot was not out of the question.
In addition to that, Bilic had bought well - Pedro Obiang, Manuel Lanzini and Dimitri Payet, for instance - and Reece Oxford had made his Premier League debut as a 16-year-old under him in another fact which might've endeared Quina to East London.
Speaking to The Sun in March, Quina, who is yet to make a Premier League squad this season, cited Bilic as a reason as to why he joined, but it is very possible that the under-fire manager might be sacked by November 18 - his 18th birthday - and getting him to pen a long-term deal under such uncertain circumstances could be tricky.
Tottenham is home to some of the best young players in Europe and rejecting the chance to work with Spurs boss Mauricio Pochettino would surely be more difficult a second time, given the contrasting trajectories and stabilities of both clubs.
If Quina - whose contract expires in 2019 - indicates that he will not sign on then the Hammers simply need to extract the maximum value from him and sell in January. It wouldn't be a great look if he develops into the top-class footballer who West Ham lost for free.
Obviously they would prefer to move him abroad but their hands could be tied if Tottenham renew an interest - and saying no to Spurs is much harder this time around.
