"Football today is like a business," Djourou told the Mirror. "I wish players would stay. Back in the day, players would stay at one club for life.
"Of course, we want football to be like that. I know that all of the players who left the club, like Samir and Cesc, I talked with them and they loved the club.
"Football is a business and they had better opportunities.
"Kolo has been away for a long time and he misses it. Arsenal is such a great club. It's a family. We've been together for so long now.
"People are talking about Man City, stuff like this, the money. But me, I'm really happy at Arsenal. It's different. Everyone is just happy.
"As I said, it's like a family, we're really happy, enjoy being together and that's the most important thing."
