Ruben Amorim blocked the departure of the 28-year-old Ecuadorian, Pervis Estupiñán, who could have become a Benfica player. The Lisbon club made several efforts to sign the left-back after a season in which he was not frequently used at Milan. The player ultimately stayed in Italian football, which led Benfica's Rui Costa and Marco Silva to sign El Karouani as an alternative.
