The transfer window is opening again in less than a month's time.

And that means that Fulham fans will have to get used to their teenage star being linked with a move away from Craven Cottage.

Ryan Sessegnon was rumoured to be attracting interest from Tottenham in the summer, but the Whites stood firm in the face of mounting speculation.

And soon after his 17th birthday, the youngster signed his first professional contract with the club.

Now it is going to cost another club a hefty transfer fee to prise him away from Craven Cottage...but just how much?

Who wants him?

He is probably the most sought-after prospect in the Championship, with Manchester Untied also reportedly in the market now. And in this over-inflated climate, Fulham can expect a huge offer for the left-back's services.

Manchester United are in need of a left-sided defender, and have been linked with Tottenham's Danny Rose on a number of occasions too.

And if United were to move for Rose instead, then Spurs would then be in need of a replacement.

Comparisons with Rose

The figure touted for Rose is £45 million. He's an England international, an established Premier League player, touted as one of the best left-backs in the world before his injury at the end of last season.

But at 27 years old he has ten years on Sessegnon. So what are you paying for? Experience, or budding talent?

Sessegnon is a left-back by trade, but he has been devastating when pushed further forward by Whites manager Slavisa Jokanovic. See the incredible 5-4 win over Sheffield United as an example.

He bagged his first ever hat-trick in that game, and, after a slow start to the season, really came back to the fore once more.

Gareth Bale

Remember Gareth Bale?

In that respect you could suggest he is of the same ilk as Gareth Bale - once the most expensive player in the world when he left Spurs to join Real Madrid for a reported £100 million.

Bale started out as a left-back and moved further forward to use his pace and power to devastating effect. Sessegnon loves getting forward and I don't think it will be too long before he is utilised in a more attacking role on a permanent basis.

Fulham can, in all honesty, name their price. He's a teen sensation and there are no rules in the football transfer market these days. If Danny Rose is worth £40 million plus, then why shouldn't the Whites demand likewise? After all, if he continues on the upward trajectory he is already on, by the time he's 27, Sessegnon could be garnering interest for three times that figure.
