Manchester United's quest to find Jose Mourinho's fourth major signing of the summer has proved much tougher to complete than they would have hoped.

Having completed deals for Victor Lindelof, Romelu Lukaku and Nemanja Matic relatively early in the transfer window, the Red Devils looked well placed to achieve Mourinho's target of four additions.

However, since the arrival of Matic, United have found that fourth signing rather elusive.

Speculation regarding Inter Milan's Ivan Perisic and Real Madrid's Gareth Bale has gone quiet, while Mourinho himself has eased the pressure on the club's hierarchy - in public at least.

That doesn't mean vice-chairman Ed Woodward isn't quietly working away to bring in someone else before the transfer window closes next week.

ESPN have reported the Premier League leaders remain interested highly-rated Fulham starlet Ryan Sessegnon.

The 17-year-old, who can play anywhere on the left flank, has attracted plenty of followers with his impressive performances at Craven Cottage.

And although a move to Old Trafford would represent a tempting proposition to most of the country's talented teens, Sessegnon is seemingly reluctant to make the move up north.

The same article claims that if Fulham's resistance to sell the England youth international in this window is broken, he would prefer to stay in London.

Sessegnon grew up in Roehampton, south-west London and at 17, a move to Manchester would be a huge, life-changing experience.

Instead, it is believed the Cottagers' ace would be more willing to join Tottenham than the Red Devils.

Of course, Mourinho's methods of persuasion are better than most so an agreement could still yet be reached but it is an uphill battle.

So far in his brief career, Sessegnon has made 36 appearances for Fulham and has represented England at under-16, U17 and U19 levels.
