The England Under-21 global has 18 months left on his current deal with the Cottagers and that could mean that his transfer fee could be reduced this summer.
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.
His efforts didn't go unnoticed, going on to be voted for by managers and players to win the Championship Player of the Season - all before turning 18.
Safe to say, big things were expected of the 18-year-old while making his Premier League debut with Fulham, who invested heavily in a bid to be competitive on the field. The potential rift has been noted by Manchester United, who are looking to take advantage of it in the summer, with Fulham, who are seven points away from safety, one of the mild favourites to get relegated.
Sessegnon has played regularly in both left-back and left-midfield since his breakthrough nearly three years ago, and a move to Manchester United and Tottenham was hinted at when the Fulham man revealed his footballing idols.
Not loving the football and the bench life at Fulham.
However, his opportunities under current coach Claudio Ranieri have been limited of late, and he only came on as a late substitute in the 3-0 defeat to Manchester United.
And the Red Devils have hope of snatching the teenage talent from the Cottagers with his contract talks stalling. While Sessegnon has evolved into a left winger, he has been played all across the left side, with left-back his natural position.
"When I was younger I had two players: Luke Shaw and Gareth Bale", Sessegnon said in 2018.
But should the Londoners fail to escape relegation, Sessegnon, 18, will be sure to attract the attention of the Premier League's big boys. A Manchester United win is [1.65]. There will be other suitors, though.
