Man United Set to Pocket £18M From Summer Sale Sell-on Clause
Manchester United are poised to pocket close to €18 million from Álvaro Fernández Carreras’ potential transfer to Real Madrid, thanks to a smartly negotiated sell-on clause inserted in the left-back’s deal to Benfica.

The Spanish defender, who joined Benfica from Manchester United in 2023, has enjoyed a breakthrough spell in Portugal, drawing the attention of European giants. Real Madrid are reportedly finalizing a deal to bring the 21-year-old back to Spain, with a transfer fee estimated around €35 million.
Due to a 50% sell-on clause included in the original agreement between Manchester United and Benfica, the Red Devils stand to receive nearly half of the incoming fee — a potential windfall of €17.5 million. The clause was part of a broader strategy by United to secure long-term value from young talents who may not immediately break into the first team.
Fernández Carreras, who joined Manchester United from Real Madrid’s academy in 2020, showed promise during his time with the club’s youth and reserve sides but never made a senior appearance. His development in Portugal, however, has turned heads and now presents United with an unexpected financial bonus.
The deal could be finalized in the coming days, with Real Madrid keen to bolster their left-back options following recent injuries and aging personnel in their defensive ranks.
This move not only shows the growing reputation of Fernández Carreras but also underlines the importance of strategic sell-on clauses — a method increasingly used by top clubs to ensure future financial returns from emerging talents.
Manchester United’s academy, widely regarded as one of the most productive in Europe, may not have seen the Spaniard shine at Old Trafford, but his rise elsewhere is now proving to be lucrative for the Premier League giants.
