#6 Saul Niguez (Jan 2016: €25 million, Now: €58 million)
Increase in Value: €33 million
One of Atletico Madrid’s gems, 22-year-old Spaniard Saul Niguez has gone from strength to strength since Jan 2016, cementing his place as one of the best young midfielders in Spain at the moment. A versatile player, Saul is capable of turning a game on its head with moments of brilliance and he is one of Simeone’s most trusted men.
Blessed with silky feet, great technical skills and most importantly a never-say-die attitude, Saul has attracted attention from some top clubs across Europe with Jose Mourinho’s Manchester United and even La Liga rivals Barcelona interested in securing his signature.
With the 22-year-old more than happy to play at Atletico Madrid at the moment, only a monumental bid well above his market valuation might get the Rojiblancos thinking about his sale.
