Enzo Fernandez says he has no regrets over his move to Chelsea.
It's now a year on since his arrival from Benfica for over 110m.
"The first six months were difficult, the second part of last year was better," Enzo told the club's website.
"That the current coaching staff speak Spanish has helped me a lot. I am working to get to my best level and hope I can meet the club's expectations of me. I'll keep doing my best.
"People have been so welcoming since I arrived here. I'm very happy and my family is too which is very important."
He continued: "My team-mates are so important to me. They have helped me a lot; I'm happy they're my team-mates.
"I did my best to integrate myself into the group as quickly as possible. I've been here a year now and the group is really united. There are some great people here.
"I've been here for a while now and I've always tried to give my best for the group so that everyone does well.
"But, obviously, it's a process and it's going to take us a while to get to our best, but we are trying to do it as fast as possible."
