According to Duncan Castles, Tottenham will be forfeiting 15% of their sell-on clause for Marcus Edwards after negotiating a deal for Pedro Porro with Sporting CP.
It is thought that Porro will sign for Tottenham on deadline day.
The London club had held the rights to 50% of Edwards’ next transfer fee, but they have now agreed to give up part of their stake, reducing it to 35%.
This move could be seen as a risk for Spurs, especially given the increasing trend of inflated transfer fees in the modern game.
Edwards has been impressing for Sporting in Portugal, where he has been showing his impressive skills in the Primeira Liga and also in the Champions League.
Tipped for the Ballon d’Or in the future by one of his former Spurs teammates, Edwards could easily be worth a fortune in years to come, and 15% of his future transfer fee could represent millions of pounds.

A young, English winger likened to Lionel Messi, Edwards could well be a £50m player in the future, and if he were to move for that sort of fee, Spurs would now be missing out on £7.5m.
On the other hand, Tottenham’s forfeiture of the sell-on clause could be a tactical move.
One would imagine it has allowed them to sign Porro on more favourable financial terms, potentially freeing up some extra cash to spend on deadline day.
While the decision to give up part of their sell-on clause may raise questions, it is clear that Tottenham are determined to make their mark in this transfer window.
The signing of Pedro Porro could be the first of a couple that the club has in the pipeline on deadline day amid links to Nicolo Zaniolo and Piero Hincapie.
Regardless of the outcome, Tottenham’s forfeiture of part of their sell-on clause for Marcus Edwards is certainly a bold move, and one that they could live to regret. It remains to be seen whether this will prove to be a wise decision in the long term, but for now, Tottenham are seemingly focused on the here and now.
