Tottenham Hotspur may have sold Cristian Romero and Djed Spence for modest fees, but they stand to earn more from the two defenders in the future.Romero has completed a £34m switch to Atletico Madrid, bringing to an end his five-year stay at the club, with the writing on the wall for the Argentine since the start of the summer.Meanwhile, Spurs have sold Djed Spence to Inter Milan for £30m, with the full-back set to return to Serie A, two years on from his loan spell with Genoa.Not all Tottenham fans are happy with the fees the club have sold the defenders for, but the Lilywhites may stand to earn more from the pair in the future.(Credit @thefrederikkejensen / Instagram)Tottenham’s sell-on clause for Cristian Romero and Djed Spence revealedAlasdair Gold has now confirmed the fees that Tottenham will get for the Argentine and the Englishman, and has also revealed that the club have retained a sell-on clause for both players.He states that Spurs have attached a 10 per cent sell-on clause on Spence, which means that they will get one-tenth of any future fee that Inter receive for the player.For Romero, Tottenham have a 15 per cent sell-on clause on the profit that Atletico make on the centre-back, rather than the whole fee.For example, if Romero is sold for £45m in the future, that means that Spurs will be owed 15 per cent of the £10.8m profit that Atletico make on the player (£1.6m in this instance).Gold wrote on X: “Cristian Romero and Djed Spence depart Spurs for £34.2m and £30m packages respectively, including add-ons. Understand Romero has a 15 per cent sell-on clause for future profit if Atletico sell him. Spence has a 10 per cent sell-on but on the full amount if Inter sell him rather than just profit.”Cristian Romero and Djed Spence depart Spurs for £34.2m and £30m packages respectively, including add-ons.
