The Arsenal manager is set to step down at the end of the season and watched his side in action for the final time at The Emirates on Sunday afternoon.
Wenger confirmed that he will be leaving Arsenal after 22 years in charge at the north London club last month.
Celebrity Arsenal fan Morgan has been one of Wenger’s fiercest critics in recent years after the Gunners’ failure to challenge for the Premier League title in recent seasons.
Arsenal finished fifth last season and are on course to miss out on a top-four finish for the second campaign running this term.
The Gunners have not lifted the Premier League trophy since their famous unbeaten triumph in the 2003-04 campaign at Highbury.
And reacting to Wenger’s final game in charge at The Emirates, Morgan wrote on Twitter: “[Wenger] left us 6th in the Premier League, having to qualify for the Europa League, and with a squad full of very average, overpaid wastrels.
“Let’s keep things real about Wenger’s legacy, not rose-tinted. Great for first 8yrs, mediocre for next 12, very poor for last 2.”
Morgan added: “Sentiment has ruled the day with Wenger for way too long, to the club’s detriment.
“I wish him well for the future but can’t feel anything but relief he is going.”
Arsenal are yet to confirm who they will be appointing as their new manager after Wenger.
The Gunners will play their final Premier League game of the season next weekend when they travel to Huddersfield Town.
