With Arsenal supporters already known to be frustrated with the transfer activity at the Emirates Stadium, reports emanating from Spain seem to touch their nerves as they claim that their favourite in Nacho Monreal could move back to his homeland this winter.

The former Malaga fullback reportedly caught the eyes of Athletic Bilbao this summer, with their interest going to the extent of the player reaching an agreement only for the transfer to be blocked by Arsene Wenger. Express now claims that they could come knocking for him again in January.

Even though the player is believed to be keen on San Mames Stadium switch, the transfer can come to fruition only if the Gunners bring in a top-notch replacement. Given the indifference that their manager usually shows towards January transfer window, one can expect the saga to drag on at least until next summer.

In the unlikely event of the 29-year-old heading for the exit door despite his frequent claims of being happy at Arsenal, Kieran Gibbs can be expected to fill his shoes. As the Englishman is no stranger to Premier League football, the London side will not be entering a period of defensive crisis.

Nacho Monreal has taken up where he left off last season as he boasts an average rating of about 7.20 so far this season. Arsenal will undoubtedly try to keep hold of his services at all costs unless they identify someone exceptional to replace him.
