Cesc Fabregas insists Arsene Wenger is the right man to lead Arsenal, and cautioned the club against bringing in a new manager, as the north London side head for a seventh successive season without a trophy.
Fabregas left the Gunners for Barcelona in the summer but admitted he still monitored the club's progress from abroad, and believes Wenger is the only manager who can turn around their troubled campaign.
Arsenal recovered from a 4-0 Champions League defeat at AC Milan and an FA Cup exit against Sunderland to defeat rivals Tottenham 5-2 at the weekend and Fabregas said there are promising signs of recovery at the Emirates Stadium.
"If I can't see Barca without Pep (Guardiola), I see Arsenal without Wenger even less," the Spain midfielder told Gazzetta dello Sport - via the Daily Mail.
"He has been there for 16 years; he is the only Arsenal coach I have known. It would be strange, very strange to see Arsenal without Wenger.
"I feel sad when I see Arsenal lose. But in football things can change from one day to the next and I am sure that a great club like Arsenal will soon be back on track."
And Fabregas faces a nervous wait to learn the fate of his current boss at Barcelona. Guardiola's contract runs out at the end of the season and he is yet to make a decision over extending his stay at the Nou Camp.
Barcelona currently trail Real Madrid by 10 points in La Liga and Guardiola has said previously that he would like to manage abroad at some point in his career.
And after winning two Champions League trophies, three La Liga crowns the former Spain international may consider a move to the Premier League or Serie A at the end of the current campaign.
"We are used to winning - and doing it with him," said Fabregas. 'We are used to his passion, his playing style, his way of coaching, of viewing football, which is different from other coaches.
"I think that if we do things right, if we continue to strive, to fight, if he sees that we have the same desire to keep winning, there won't be any problems about him staying.
"Maybe he thinks we got tired or that he can't bring out the best from us, or that we are tired of him, but that's not the case. We are 100 per cent with him.
"Pep makes everything very simple, he asks only that strive to be the best you can.
"Personally, I'm learning a lot and would have for him to go because when I signed I hoped I would work with him for a long time."
