Edu, a member of the Arsenal 'Invincibles' side, insists it will take time for Arsene Wenger's new-look team to gel together.
The Brazilian, now manager of Corinthians, played a pivotal role in the Gunners' side which went 49 league games unbeaten, including the entire of the 2003/04 season.
Despite playing with the likes of Thierry Henry, Dennis Bergkamp and Patrick Vieira, Edu admits it even took a team possessing those stars, time to gel.
“There are some big changes,” Edu said.
“They have sold two or three important players who are difficult to replace.
“For me, to build a good team you need time - like in our time. I remember for three or four years we were playing together and that is why we built a very good, strong team.
“They need the time and that is maybe why they are not doing so well yet.”
Amid the changes at the Emirates Stadium, Arsene Wenger has received much criticism for Arsenal's uncertain start to the season, but Edu, the newly appointed Corinthinians boss says he's taken on the advice the Frenchman gave him during his playing days.
“Yes I have spoken to him but the advice he gave to me was during the times I was with him,” Edu added. “They were great times, I learned a lot and I told him this week that everything I learned was from him.
“Now I am manager of Corinthians it is quite different to managing in England. In Brazil we have a coach and then a manager. The coach looks after the team on the pitch and the manager looks at everything around that - they have to sign players and get other things done.
“But I learned a lot of things from Arsène Wenger and many things in Brazil too.”
