Enzo Fernandez has been given permission to undergo a medical in Portugal.
According to sources in Portugal, who asked not to be named because of their proximity to the situation, there is now heightened optimism that an agreement can be reached between Chelsea and Benfica.
As a result, Benfica have agreed to let Fernandez undergo a medical in Portugal for the event of a deal going through.
Chelsea have been pursuing the Argentina midfielder throughout the January window. They renewed their push to bring him into Stamford Bridge on Monday and have been speaking to Benfica throughout Tuesday as they look to make a breakthrough.
Fernandez has a €120million release clause in his contract with Benfica.
The 22-year-old only joined Benfica last summer from his boyhood club River Plate and has made 17 appearances for the Portuguese side. He starred as Argentina won the World Cup in Qatar last month.
