Wenger has spent 22 years at the north London club, winning three Premier League titles and seven FA Cups, though the latter years of his tenure have seen Arsenal fall out of the top-four places.
Their only chance of silverware this season is in the Europa League, and if they fail to win the competition they will miss out on a Champions League berth for a second consecutive season.
Many fans turned on Wenger in recent seasons, with Wenger Out protests held and banners flown over the Emirates on planes asking for him to resign.
And now Beckham has posted a tribute to Wenger in which he calls for the Frenchman to get the respect he deserves and lauded his rivalry with Manchester United at the turn of the century.
Beckham posted on Instagram: Maybe this man will now get the respect he deserves for 22 years of bringing great players, great football and a great rivalry for us, Manchester United, to the Premiership.
Its now time to celebrate everything that Arsene gave to Arsenal football club.
Beckham and Wenger faced off countless times for Manchester United and Arsenal in what was one of the defining rivalries of the Premier League, and the former England international is frequently seen at the Emirates watching the Gunners.
