The 29-year-old is slowly reaching his ending stages of career and could be spending his last three years at the Emirates Stadium.
Monreal has been a vital part for the Gunners for the past few seasons. He has been a regular player for the Gunners since 2013. He has featured in all the eight games in the Premier League so far this term.
Meanwhile, another full-back Kieran Gibbs is expected to leave the Gunners due to lack of playing time on the pitch.
Gibbs has just made two appearances in the Premier League so far this season and could be further struggling in the future as Monreal has signed a contract extension.
