De Jong: "Paris would've been a top choice. They impressed me. Good club, team, coach... Biggest chance to play. Ligue 1 could've been an advantage, as you've time to grow. But Barcelona has always been my dream and La Liga has more quality."

"I went to Manchester and Paris and spoke with Tuchel and Guardiola. My choice ain't a decision against those clubs, but in favor of Barcelona. The challenge is great. Spain is top. France too, but you don't have the feeling you wanna play there for ten years."

"Perspective was key. It was the reason why I was a bit reserved about Barcelona. I thought: they have so much midfielders, it's a hard job to earn your place. But FCB gave me the right feeling. There are no guarantees, but my chances are positive."

"Busquets is the best CDM in the world and will play for a few more years, so I won't make any illusions. Barcelona see me on all three positions in midfield, but short term in front of Sergio. I go to FCB to become a starter, but won't say anything."

"Of course it's beautiful to play alongside Lionel. But at the moment, I can't say anything about it. I have never played with him. Everyone knows I think Leo is the best, but you must not go too far. The key factor in this transfer was Barcelona."

"When I work hard, learn the language... Then I can't blame myself. If it doesn't work out, I will try somewhere else. I am only 21 years of age and still developing. When all goes right, I will only become better."
