Arsenal have reportedly agreed a £6m fee with Malaga for left-back Nacho Monreal.
The 26-year-old will now make his way to North London for a medical, according to Spanish newspaper AS.
Monreal has started 14 of Malaga's 21 games in La Liga this season, while also adding to his caps (nine) for Spain.
However, he will be unable to play in the Champions League as he is cup tied. That means Andre Santos would still be likely to face Bayern Munich, with Kieran Gibbs still missing with a thigh injury.
