Boca Juniors chief Nicolas Burdisso says the door will always be open to Arsenal midfielder Lucas Torreira.

Torreira has spoken of his admiration for Boca.

And the Superliga club's director Burdisso said in response: "Torreira? It is lovely to hear him talk about the club with such affection, but he's just moved to Arsenal and signing him now is impossible.

"It is one of those cases where the player has to make the first move.

"We will wait for the right moment."
