Chelsea have agreed a £105m deal in principle with Benfica for Argentina midfielder Enzo Fernandez.
Chelsea have been in talks to sign the World Cup winner throughout this month but Benfica had refused to do business unless the Blues paid his €120m (£105m) release clause.
Should Fernandez’s deal to Stamford Bridge go through without any problems, the transfer will surpass the £100m Manchester City paid for Jack Grealish from Aston Villa 18 months ago, making him the most expensive Premier League signing ever.
