Speaking to the official Chelsea website, Fernandez said: "I’m trying to get there, to the version of me that you saw at the World Cup. I want to feel like that Enzo, that was playing at the World Cup. I want to get back there. I feel good, getting better each day, but I still don’t feel like I’m at 100 per cent. I’m still adapting and still don’t feel entirely myself, but I’m trying to get there as quickly as possible and working hard every day in order to do so.
"Maybe personally I’m still not 100 per cent and don’t feel like I’ve shown my potential, but beyond that I love being at a club as big as Chelsea, enjoying the Premier League every weekend with the fans that are so passionate. I love being here."
