The 24-year-old has established himself as one of the most closely watched defenders in Bulgarian football and is drawing attention from clubs back in Brazil as well as elsewhere in Europe.
Torino, who are actively searching for a defender fitting this profile, have shown interest, with Ryan himself said to be keen on a move to Italy. Technically, he is viewed as closer in style to Arsenal's Gabriel Magalhaes than to Bremer, the Brazilian centre-back most commonly referenced when Torino's search for a defender comes up.
Torino are not alone in tracking him, however, with clubs in Russia and Turkey also interested, alongside a leading side from Poland's top flight. That level of competition means any deal for Ryan is unlikely to be straightforward, even with the player's own stated preference for a move to Serie A.
Torino's defensive rebuild has been a summer priority, with the club having lost several centre-backs from last season's squad and head coach Ignazio Abate keen to add fresh options before the campaign begins.
Sporting director Gianluca Petrachi's scouting network has increasingly looked beyond Italy's traditional recruitment markets in recent windows, and Ryan's situation fits that broader pattern, with Torino hopeful that his stated preference for Serie A can help them win the race for his signature despite the level of competition involved and the financial demands of the deal.
