Arsenal captain Pierre-Emerick Aubameyang admits exchanging messages with Emi Martinez ahead of the goalkeeper's return today with Aston Villa.

The Argentine will come up against Gabon international Aubameyang, who he knows well from his time at Arsenal.

The former team-mates have exchanged words ahead of Sunday's match and Aubemyang has joked about telling the goalkeeper what he plans to do.

“He knows [the secrets], but I've got no worries about that," he told Arsenal's official website.

“He knows a lot of things, but things can change on the day of the game.

“Emi is a great keeper and a great guy as well.

“It's going to be funny to play against him.

“He sent me a message and said, 'Hopefully you're going to get a penalty and I'm going to save it.'

“I said, 'OK, be ready for the chip then!'"
