Arsenal's poor start to the Premier League season lurched to a new low on Sunday evening after Mikel Arteta's side were beaten 1-0 at home by Burnley.
An own goal from captain Pierre-Emerick Aubameyang was enough to see the visitors record their first ever Premier League win at the Emirates, and heaped further pressure on first team manager Arteta.
The Gunners boss has faced a series of complications in his first full season in charge in north London, not least the ongoing situation with teenage defender William Saliba.
After rejoining Arsenal after a season-long loan spell at Saint-Etienne last year, the 19-year-old was expected to compete for a place in Arteta's first team plans this campaign.
But Saliba is still yet to make a competitive appearance for the Gunners, and recent reports have claimed that Arsenal could send the defender out on loan in January to gain some experience.
Saliba himself, has poked fun at his situation and lack of minutes on social media.
And Edu has now admitted that the centre-back still needs time to develop before he is ready for Premier League football, and urged supporters to be patient.
"Maybe he needs a little more time," Edu told supporters at a fans forum meeting on Tuesday night.
"He’s a bright talent. We need to talk with him and Mikel to plan for next year."
The Brazilian also dismissed reports that the Arsenal dressing room are growing disgruntled at Arteta's regime.
"I try to be as open as possible," Edu said. "I like to hear from you. As a Brazilian, I’m very open. I’m not scared to say things.
"We’re are not comfortable in this situation we’re in. Every single club has problems. The stories about a split between the players and Arteta are not true.
"Stories about players not believing and not trusting Mikel are not true."
