The Guardian’s Jonathon Liew told Sky Sports News:
“If you’re a top class club, if you’re a club that’s aspiring to play cup finals, Champions League finals, like Chelsea are, a World Cup, especially the sharp end of it, can tell you a lot about a player’s mindset.
“Everybody knows what Enzo Fernandez can do, he’s done it in the Champions League for Benfica, he’d done it for River Plate. But seeing how he does in that cauldron under the pressure of a World Cup final, that does actually tell you a lot about that player. And anybody who saw Fernandez at the World Cup would have liked what they saw.
“He’s got a £106 million release clause and Benfica obviously won’t want to let him go in January because they have a Champions League campaign of their own to pursue. But they will probably know that he is at the peak of his value, so if Chelsea can stump up the cash then they can make the deal happen in January.
“Kante’s deal is up at the end of the season, Kovacic has been playing through injury, Jorginho, as well, up at the end of the season, so it all makes sense.”
