Barcelona signing Alex Hleb believes Arsenal will struggle to cope if Arsene Wenger ever chose to leave.
"Wenger is everything to Arsenal," he told The Daily Telegraph, "The future for Arsenal, if Wenger stays, is that they will always play at the top.
"But of course it is difficult now because Arsenal have a few political differences. When he leaves, I think this is a difficult time coming for Arsenal."
Hleb has backed Barca's interest in his former Gunners teammates Emmanuel Adebayor and Cesc Fabregas.
He told the Daily Telegraph: "Every team would like to keep these players. For me it would be fantastic if they came to Barcelona.
"Those players would bring good energy and power to this club. For Barcelona, it would be fantastic, and for me personally as well, if they leave.
He added: "Sometimes I think that Arsenal do not want to keep this team, not give something more."
Panathinaikos signing Gilberto Silva admits he's sad to be leaving Arsenal.
"I feel a bit sad, you know. I like many, many people at Arsenal and it has been fantastic this last six years at the club," Gilberto told Arsenal TV Online. "The good thing between us, me and Arsene, is that we have been clear in our conversation to play, which is normal because in the season before I played a big part.
"He told me in case I decide to leave he wouldn't stop me. It was my decision, he wanted me to stay, but at the end I didn't know, to be honest, if I would have a chance to play.
"Then I had this opportunity at Panathinaikos and I felt it was a great one in terms of playing games and a contract.
"I have three years there, when I only had one year left at Arsenal. I considered all these things to get this opportunity.
"It is fantastic because even though I haven't played much this year, at this stage [of my career] I have this opportunity to play in another club.
"It means over the years I have done the job well and people still believe in me."
Gilberto Silva also admits he doubts if Arsenal can win a trophy this season.
"This is what they need to achieve - start to win things," the new Panathinaikos midfielder told Arsenal TV Online.
"Of course there is massive pressure on them but people cannot forget they are still a young side and they have a lot to improve, to grow and to learn, but it will be very important to them if they win something this year.
"I am sure everyone at the club, Arsene, his staff, the players will do the maximum they can to achieve and win titles. This is the target and they won't change it.
"But it will be hard again. It won't be easy because the other teams are stronger than last year and Arsenal will have a hard season but I am confident they will handle it. I hope they can win this year."
