Arsenal boss Mikel Arteta has hinted he knows the identity of a dressing room mole.

Arteta warned there would be "consequences" for any Arsenal employee who had spilled the beans on a training ground bust-up involving Dani Ceballos and David Luiz earlier in the season.

Two months on, the Arsenal boss was quizzed on whether his detective work had borne fruit.

"I have sort of an idea, yes," he said.

When pushed on whether it was related to the players who left this month, such as Mesut Ozil and Sokratis, he added: "No comment on that."
