He told the club's official website: "It’s a chance for me to find a home. After two loans, Chelsea and Barca, I needed to stay permanently in one place. There is no better place for me to be than Chelsea. I see a perfect place to shine. It was a little bit of a lot of things that made me want to come back: the project, the club, the league, the fans, the time I spent here that I loved. I felt really good when I was here, despite the results we had. I’m really happy to be back.
"I’ve developed as a player in a lot of ways: the perception of the game, and the spaces the ball can arrive easily where I can make more impact. I try to figure it out by watching some videos of me of my games. I’ve kind of changed since I was last here. I’m 24 now. I’ll be 25 in November. I feel like I grew up as a player. That’s normal with age. I’m more prepared for the Premier League. I feel like my best years are ahead of me. I have no doubt about that. The best years are still to come. And this year is going to be a good year, because now I am permanently at home, and I can enjoy home."
