Jens Lehmann has warned that any prospective Arsenal takeover involving his former teammates needs to get the structure of the club right.
Thierry Henry, Dennis Bergkamp and Patrick Vieira are helping Swedish billionaire Daniel Ek in his proposed takeover of Arsenal, following fan protests after the Super League failure last week.
Lehmann is unsure whether Stan Kroenke would be willing to sell Arsenal but says he would welcome his three former teammates returning to the Gunners.
Yet, pointing to his own experience on the board at Hertha Berlin, the former goalkeeper warned that any involvement Henry, Bergkamp and Vieira have must be in the right area of the club.
He told Sky Sports: "It would be fantastic to have my former teammates working for Arsenal again because they're all great guys.
"But I don't know if the Kroenke family actually wants to sell Arsenal. From my encounters with Josh Kroenke, he's a very nice guy and he was very interested to lead Arsenal to a brighter future.
"My experience of football, now I'm on the board at Hertha Berlin, is people first need to know the right questions and then implement a structure where all the guys - Thierry, Dennis and Patrick - can work.
"There's Edu, a former team-mate, I think he's doing a good job there. So if on top comes Thierry as a coach or manager probably, Patrick the same. Dennis was an assistant coach at Ajax."
Lehmann also praised Gunners fans for the way they stood up against the Super League and protested the club's owners.
"It was the power of the fans, who didn't see the competition aspect in the Super League," he said. "So it tells you the fans are quite keen about fair competition, even though it means that Arsenal would probably not play in the Super League or the Champions League next year.
"Everybody loves to have competition, which is the basis of the game in Europe.
"The fans have a very sensitive attitude about it and it absolutely needs to be respected.
"That's why I love the Arsenal fans, because they know that it's very hard for Arsenal to get back into the Champions League, and still they are against it."
