When I joined Arsenal in 2000 I learned a lot from Dennis Bergkamp. He was the mind of the team and he made things look easy.
It's never easy to switch from one football to another one, from one culture, one language to a new one.
Fans should remember Thierry Henry when he joined Arsenal. He didn't score much before becoming an icon of this club.
Everyone benefits from a strong Paris Saint-Germain - the club itself, the French league and also the Champions League.
In France, the gastronomy is one of the best in the world. But when you move to England, everybody tells you to be careful about fish & chips. And avoid fried English breakfasts. I now know why.
I never watched British television. I bought myself a satellite for French, Spanish and Portuguese TV, instead.
It was very hard to finish my professional career. But it's OK, I really had played for as long as I could - I was 41 when I played my last match, in India, for FC Goa.
Football is unique because it enables you to travel, learn about other cultures, meet new people and speak other languages.
Going to play in India at the end of my career was particularly special. I never thought I would get the chance to even visit India, let alone play football there.
You know when you play for Arsenal, if you want to play for Arsenal, you need to be very, very good.
For Arsenal it's very important to have a player like Matteo Guendouzi. He's a good player and I think he can make a success with Arsenal. I hope so. He's a great player, he's very talented and he's very confident.
My time with Arsenal at the beginning was very difficult. Adaptation is very important and it was very long for me. But Arsene Wenger helped me during five or six months.
I learned everything in France, I grew up in France, but England is not the same football. It's very difficult, it's very tough, very physical.
I love Lucas Torreira. When you play in his position you need to be a warrior, and he's a warrior. He likes to fight a good fight with the other players and technically he's very good.
Being at meal time on time is simple but important for the team. You need the discipline. Every top club is like that. With Arsenal and Villarreal it was the same - strict.
In France, it is important to work every morning on the tactical. Wenger worked every morning on the tactical.
Liverpool is a great club and I always enjoyed playing at Anfield because the fans are so passionate.
You can be a manager in Spain, France or Italy but when you come to England the intensity is totally different. It is about the fight, the spirit. The intensity is extremely difficult.
If you want to build a good team, you need to spend a lot of money, especially in the Premier League.
All the top clubs want to sign great players, but if you want a great player it costs a lot of money.
Arsene helped me off the field too. He was like a second dad to me. He loved a player with very good quality and ability with the ball. That's why he enjoyed Thierry Henry, Nwankwo Kanu and Bergkamp.
I enjoyed playing against Chelsea, Manchester United and Liverpool but the north London derby was totally different. I have so many great memories from this fixture.
To win the World Cup in your own country was magical. When Didier Deschamps lifted the trophy, I thought: 'Wow, I'm a very lucky man.'
