Arsenal defender Nacho Monreal has reportedly emerged as a transfer target for Athletic Bilbao.
At the start of the season, Monreal was linked with a return to La Liga, but the player has since gone on to become one of Arsene Wenger's most consistent performers of the campaign.
The 31-year-old has made a total of 20 starts in the Premier League, but it appears that his form has led to interest from Bilbao.
Real Sociedad defender Inigo Martinez has also been linked with a transfer, but it has been suggested that Monreal is likely to emerge as the main target.
Monreal previously spent time at Osasuna and Malaga before signing for Arsenal in 2013.
