Arsenal are watching Watford reject Miguel Layun.
AS says Arsenal have already brought in Stephan Lichtsteiner to strengthen their options in the full-back positions.
And they could move for Layun too as they prepare to challenge on four fronts next season.
Arsenal took note of Layun's performance as Mexico secured a shock win over Germany at the World Cup.
And they have made their interest in the former Watford ace known by getting in touch with his representatives.
Arsenal will have to wait and see if Sevilla exercise their option to purchase Layun from Porto having had him on loan this season.
