He has since dropped to the Championship with the London club, where he is expected to play a big role under Felix Magath over the coming months.
But Liverpool are plotting to land him, and are ready to send him back on loan to Craven Cottage as a part of the deal.
Although Chelsea could offer him the chance to stay in his current city and Manchester United are renowned for their nurturing of young British talent, Roberts is understood to be a Liverpool fan, while his parents also hail from Merseyside.
The Reds are also ready to use the examples of Raheem Sterling and Jordon Ibe to convince the England U-17 international to pick Anfield, with the duo – also wide attackers – having broken into the club’s first-team under Brendan Rodgers.
Roberts is keen to play regularly at this time, so the Premier League runners-up will allow him to re-join Fulham for at least the rest of the season should an agreement be reached.
