Arsenal behind the scenes: Unai Emery's January priority, Nelson return, Dembele latest & Pavon

The Premier League returns this weekend with Arsenal heading to Bournemouth on Sunday looking to extend their unbeaten run to 17 games in all competitions.

It's been a fine start to the season for the Gunners under Unai Emery, but now they will be really trying to kick on as we head towards the busy festive period and the January transfer window.

Ahead of their return to action, Arsenal writer Charles Watts gave his thoughts on some of the big talking points at the club right now during a Q&A with fans on Thursday - Here is what he had to say on what is going on behind the scenes in north London.

On what Arsenal and Sven Mislintat's transfer priority is

Charles Watts: "The plan at Arsenal was they weren’t going to do any business in January and then target two key areas in the summer - wide attacker and left-back.

"Obviously, the injury to Welbeck has changed that and they really do need to bring someone in now in January because they are very short on attack and will be overly reliant on Auba and Laca.

"The summer budget was going to be around £50m, before any player sales. Which is fairly similar to what it has been in recent years. I think they will add to that by getting rid of players like Elneny and possibly Kolasinac.

"A new left-back will certainly the priority in the summer. I could see another central midfielder coming in as well."

On a possible January return for Reiss Nelson

Charles Watts says: "A lot depends on whether they think they could bring anyone in. If it looks like landing one of their key targets is unlikely, then Nelson could be an option to return as cover for Welbeck.

"Ideally, Arsenal want him to remain in Germany for the season as they see that as best for his development.

"But there is a possibility of him coming back in January. There is usually a one-week period in January during a season-long loan where the deal can be cut short.

"So Arsenal would have to make a decision there and then. As it stands, I think he will stay with Hoffenheim."

On the possibility of Ousmane Dembele signing from Barcelona

Charles Watts says: "I’m afraid I can’t see it happening. Arsenal just can’t afford him.

"They want him, make no mistake about that, but the money it would take to prize him away from Barca is just out of Arsenal’s reach right now.

"The only way they could do it is if Barca allowed him out on loan and then they struck some sort of payment deal that was structured over several seasons.

"That’s not out of the realms of possibility, but I would be very surprised if it happened.

"If Barca sell Dembele they have to pay Dortmund £26m. That tells you how much they would need to do business, even with his disciplinary issues.
