Whether that uncertainty will affect their transfer policy remains to be seen, although given Sessegnon's age and potential it's likely the club will be in for him regardless, particularly if Fulham are unable to escape their current relegation predicament.
And Manchester United are said to be aware of the case as they keep tabs on his situation.
The Reds got to see Sessegnon up close when he was introduced as a substitute in the final stages of Saturday's 3-0 victory at Craven Cottage and are reportedly buoyed by the fact that his contract talks are not progressing smoothly.
The January transfer window is closed but managers are still looking ahead to the summer so we'll bring you all the latest news and gossip from around the globe.
They report that United are ready to spend big on the English teenager, who is struggling to force his way into Claudio Ranieri's Cottagers starting lineup at present.
United arrive in SW6 as the Premier League's form team, but Ranieri wants to see his troops make life as hard as they can for Ole Gunnar Solskjaer's men.
A brace from Paul Pogba and a sensational solo goal from Anthony Martial were enough for the Premier League's form side, who have picked up 25 points from nine games since replacing Jose Mourinho with Solskjaer in December. "There are big games coming up and that will decide where we're going to stay at the end of the season".
Marcus Rashford has made 8% of his total Premier League appearances under Ole Gunnar Solskjaer (8/100). Only versus Arsenal (5) and Charlton (4) has Ranieri lost four consecutive Premier League games versus a single opponent.
Rumours circulated that Sessegnon may be set to leave last summer, with United just one of a number of high-profile clubs who were linked with his signature.
He became the first player born after 2000 to score a Premier League goal when he netted against Cardiff in October. The draw half-time/Manchester United full-time double result is [4.9].
