BBC Sport journalist David Ornstein claims that Arsenal have tried to sell Shkodran Mustafi “almost every window since they signed him”.
The Germany international has come under criticism for some of his performances over the last season or two, with the Gunners defence one of the leakiest in the Premier League’s top ten last term.
“The suggestion is he’d be loaned back for a season which wouldn’t be ideal as they need a centre-half now. There’s no confirmation on that but talks are ongoing.
“I was told that after the Europa League final that Unai Emery, who had always put his faith in Shkodran Mustafi despite a number of high-profile mistakes, has decided enough is enough with him and he is no longer in favour of keeping him, so he could be sold.
