Sources: Sell-on clause inserted in Leeds player sale as Huggins fee revealed

Leeds United agreed to let Niall Huggins join Sunderland for free but inserted a sell-on clause into the deal, Football Insider can exclusively reveal.

The 20-year-old full-back joined the Black Cats from United last month in a deal first revealed by this site.

Huggins penned a four-year deal with Lee Johnson’s side after his pathway to the Leeds first team was blocked by an army of talent.

A Leeds source has told Football Insider that the club will not receive a transfer fee from Sunderland for Huggins even though he had penned an improved three-year deal last December with the Whites running until 2023.

However, United chiefs have protected themselves from the possibility of their academy product blossoming into a top-tier talent on Wearside with the sell-on clause.

It means Leeds will get a significant portion of the fee should Huggins leave Sunderland at any point.

There was an exodus of young talent from Elland Road during the summer transfer window.

As first revealed by Football Insider, youngsters Robbie Gotts, Jordan Stevens and Bryce Hosannah all made permanent moves away from Leeds on deadline day.

Midfielder Gotts and winger Stevens both joined League Two Barrow on free transfers, while Hosannah joined Wrexham on a free.

At Sunderland, Huggins is still waiting to make his League One debut.

But the Wales Under-21 international made his competitive bow for the club in their 3-2 EFL Cup win over Blackpool on 24 August.

Huggins made 17 appearances for the Leeds Under-23s last term.

He then went on to make his senior debut as a second-half substitute in February’s 4-2 Premier League defeat to Arsenal but has not added to that solitary appearance.
