The Telegraph have reported that Atletico Madrid have added Arsenal left-back Nacho Monreal to their list of transfer targets that already included Santi Cazorla after losing a number of their title winning squad.
Atletico sold their first choice Filipe Luis to Chelsea and are eyeing Arsenals second choice left-back as a replacement.
Kieron Gibbs is Arsene Wenger's first choice left back and Monreal may want to leave for the prospect of first team football in Spain.
Arsenal will be tempted to cash in on the 28-year-old full back who is currently on £60,000 a week, proving to be an expensive back up.
Last seasons La Liga Champions and Champions League runners-up have been keen on signing Cazorla all summer but it'll take their best efforts to prize the midfielder away from the Emirates.
Cazorla may struggle for first team football since the arrival of Alexis Sanchez and could be tempted to join Atletico for the guarantee of weekly football.
The experienced left-back signed for Arsenal from Malaga in 2013 for a fee of roughly £8 million but has struggled to break into the first team ever since.
The Spanish international was a product of the Osasuna youth team and went on to make 127 appearances for the first team before moving to Malaga for 6 million euros.
Monreal has failed to establish himself in Wenger's first team since joining and has only managed to make 33 first team appearances and will be tempted to leave the club if he is offered first team football.
Cazorla is a versatile midfielder who can play in the number 10 role or on either wing, he is known for his two footed ability, passing range, shooting accuracy and sublime close control.
The Spaniard honed his skills in La Liga making 253 appearances and scoring 39 goals over nine seasons, as well as being awarded the Spanish Footballer of the Year during the 2007-07 campaign.
Cazorla signed for Arsenal in 2012 and quickly became a fan favourite, he adjusted to Premier League football easily scoring 12 goals in his first year and making 13 assists earning himself the Arsenal Player of the Season Award.
The midfielder would seamlessly slot into any Premier League side but Arsenal have a number of world class midfielders and he may face competition for a starting place in the coming campaign.
Cazorla has claimed he wants to stay at the Emirates a number of times this summer but may be tempted by the guarantee of first team football and a return to his homeland.
