#3 Giovani Lo Celso
After failing to make the grade with French Ligue 1 side PSG, Giovani Lo Celso arrived Real Betis in August 2018 on a season long loan with the option to buy.
The 22-year-old's performance was so impressive that the club activated their buy back option in April 2019.
Lo Celso was one of the driving forces behind Real Betis's impressive start to the season, dictating play from the middle of the park, with his close control and ball technique as well as precise passing proving integral to Quique Setien men's playing pattern.
In total, he made 32 La Liga appearances, scoring nine goals and creating four assists to help Los Verdiblancos to a respectable 10th place finish in the league.
His form saw him deservedly named in Argentina's 23-man squad for the upcoming Copa America as Luis Scaloni attempts to become the first manager to win a major trophy for La Albiceleste since 1993.
Giovani Lo Celso currently has a value of €40m and Real Madrid would do well to consider him rather than Paul Pogba.
