The Spanish midfielder joined PSG on a five-year deal last month for a fee reportedly worth an initial €21.5m to Napoli.
Fabian said that moving to the French capital was easy.
“The offer comes, we all think it’s very good, that you can’t say no to a club like Paris, the project they’re doing, the club, the history,” he said. “I have a year left on my contract and Napoli and I were interested in starting [talks]and I think it was a very good choice.”
Fabian is relishing the opportunity to work with the likes of Neymar, Kylian Mbappe and Lionel Messi.
“When you arrive, it’s a bit overwhelming to see the best players together, to know that you’re going to change with them, that you’re going to live with them every day,” he said. “It’s a privilege. But at the same time, it’s okay. They are normal children.”
Fabian has a lot of competition to take his place in Christophe Galtier’s side, but he is ready to take the opportunity.
“They like what I’ve been doing these years,” he said. “At Napoli, through work or luck, everything went well, both as a team and personally. They ask me about what I was doing. Order. To be orderly on the field.
“At the end of the day, I’m a player who likes to run, be up, get down, and that’s what they asked me to do, to be able to get to the zone and then be able to come back, help the team defensively, because at the end of the day, we’re very an aggressive team, we have a lot of people up top and in the middle we have to have that solidarity to be able to defend well and compactly.
“He [Galtier] asks me for both: to help them in defense, but at the same time so that he can also reach the area.”
