Chelsea midfielder Enzo Fernandez says fans are yet to see his best.
Enzo is now 14 months into his career with the Blues.
"I'm trying to get there, to the version of me that you saw at the World Cup," he told chelseafc.com. "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.
"It won't be easy because the World Cup has been and gone, and I'm still growing as a player and developing my skills, but I'm looking for that Enzo. I want to feel completely myself again."
He also said: "In my opinion the Premier League is the best league in the world. It is so dynamic with so many quality players. I think it's the best. I always saw the Premier League on television. The intensity, the atmosphere, it was different.
"Now that I'm actually experiencing it, it's incredible. The first six months were difficult for me. I found it hard to adapt but now I feel so much more prepared than at the start. But I'm enjoying it so much.
"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."
