Chelsea have entered negotiations to sign Gerson. The Blues have already completed the move of Ajax winger Hakim Ziyech and agreed on a deal with RB Leipzig for Timo Werner.
Gerson, the Brazilian midfielder, has enjoyed another excellent campaign and played a key role in leading Flamengo to their first Copa Libertadores title since 1981.
The 23-year-old also helped the club win the Serie A title, Supercopa do Brasil, Recopa Sudamericana and played 102 minutes of the FIFA Club World Cup final extra-time defeat to Liverpool in December 2019.
Chelsea are eager to bolster their midfield and according to Globo Esporte reporter Eric Faria, negotiations are well underway with representatives from Chelsea and Borussia Dortmund holding discussions with agent Giuliano Bertolucci.
Bertolucci’s involvement could give Chelsea transfer guru Marina Granovskaia the upper-hand.
