Tottenham Hotspur have been quoted a figure of £20m for Ryan Sessegnon with a further £10m required to prise away his brother, Steven, from Craven Cottage according to The Mirror.
Spurs were interested in Ryan during the summer window and with full-back Danny Rose looking set to quit the club, the youngster is their prime target to replace him.
Ryan has shown he can be utilised at left-back or further up the wing and bagged a hat trick in Fulham's 5-4 win over Sheffield United to emphasise his threat.
Steven has also shown his versatility and can play both in defence and midfield.
The North London side are believed to be leading this chase having monitored the brothers for more than two years.
Reports suggest that Mauricio Pochettino's side would want Ryan to join the club immediately but would allow Steven to return to Fulham for an 18-month period.
The Sessegnon twins both penned their first professional contracts over the summer and these run until 2020.
