#4 Alisson Becker - €60 million
Alisson has risen to fame of late, courtesy of a stellar last season with Roma where he was an instrumental figure in La Lupa's unanticipated run to the semi-finals of the UEFA Champions League.
Di Francesco's side lost out to Liverpool - the club which looks to be the most likely destination for Alisson next season.
The self evident finesse of the 25 year old can be estimated by the fact that he was given the green light ahead of Ederson for the Brazilian national team in the recently concluded World Cup.
Alisson is currently being pursued by some top notch clubs, including the likes of Liverpool and Chelsea, if a deal happens, the former Internacional star could potentially become the most expensive goalkeeper of all-time.
