[ad_pod ]According to The Mirror, Arsenal are considering a move for Liverpool full-back Alberto Moreno whose contract expires in the summer meaning he could then be available on a free.Unai Emery's current first choice full-back Nacho Monreal isn't getting any younger and the his distrust in Bosnian Sead Kolasinac has seen young midfielder Ainsley Maitland-Niles become a makeshift second-choice.Left-back Andy Robertson's form at Liverpool has seen Moreno limited to a single EFL Cup appearance so far this season, with Jurgen Klopp even likely to deploy utility man James Milner on the left side of defence ahead of the Spaniard if Robertson is injured.The 26-year-old has made 88 league appearances for the Reds, scoring three goals and assisting five, but his time at Anfield seems to be up with reports suggesting that he has no interest in renewing his contract with the Merseyside club.Emery worked with Moreno at Sevilla in the 2013/14 season but since making the switch to Liverpool the latter has been criticised for his defensive abilities, or lack of, on a couple of occasions. The fact that he might not cost the Gunners a penny in transfer fees is a positive, but not all Arsenal fans are feeling good.Here's how they reacted on Twitter.
